+Disabled Test Cases
+~~~~~~~~~~~~~~~~~~~
+
+Below is a list of all disabled test cases currently listed in
+testconfig.dat and an explanation as to why they are disabled.
+
+debug_api/debugbreak/test1
+debug_api/outputdebugstringa/test1
+debug_api/outputdebugstringw/test1
+debug_api/writeprocessmemory/test1
+debug_api/writeprocessmemory/test2
+debug_api/writeprocessmemory/test3
+debug_api/writeprocessmemory/test4
+=======================================
+The above testcases were disabled in the palsuite, because they depend heavily on
+WaitForDebugEvent,DebugActiveProcess and ContinueDebugEvent, where these api's have been removed from the PAL and listed in the rotor_pal.doc (6.0)
+
+
+file_io/gettempfilenamea/test2 :
+=======================================
+This test takes longer than 60 seconds to run. The test creates
+about 65000 files and then deletes them. The test that takes longer
+than 60 seconds will be flagged as an error and so in such a case
+the test will have to be run manually.
+
+file_io/gettempfilenamew/test2 :
+=======================================

+about 65000 files and then deletes them. The test that takes longer
+than 60 seconds will be flagged as an error and so in such a case
+the test will have to be run manually.
+
+locale_info/getcpinfo/test2:
+=======================================
+This test will be useful in future versions for testing various
+languages (code pages).  Currently only U.S. English (tested by -
+test1) is supported.
+
+locale_info/getcpinfo/test3:
+=======================================
+This test will be useful in future versions for testing various
+languages (code pages).  Currently only U.S. English (tested by -
+test1) is supported.
+
+locale_info/isvalidcodepage/test2:
+=======================================
+This test will be useful in future versions for testing various
+languages (code pages).  Currently only U.S. English (tested by -
+test1) is supported.
+
+miscellaneous/getcalendarinfow/test2:
+=======================================
+Currently the only calendars that are supported are CAL_GREGORIAN
+and CAL_GREGORIAN_US, which are tested by test1.  This test will
+be useful when full calendar support is implemented.
+
+miscellaneous/getdateformatw/test1:
+===================================
+Currently the only calendars that are supported are CAL_GREGORIAN
+and CAL_GREGORIAN_US.  The GetDateFormatW function will only be 
+called when the calendar is CAL_TAIWAN. Since this calendar is not
+currently supported in this release of the PAL, the GetDateFormatW
+function is not implemented except to return an error. This test
+will be useful when full calendar support is implemented.
+
+miscellaneous/getdateformatw/getdateformatw_neg1:
+================================================
+Currently the only calendars that are supported are CAL_GREGORIAN
+and CAL_GREGORIAN_US.  The GetDateFormatW function will only be 
+called when the calendar is CAL_TAIWAN. Since this calendar is not
+currently supported in this release of the PAL, the GetDateFormatW
+function is not implemented except to return an error. This test
+will be useful when full calendar support is implemented.
+
+miscellaneous/getdateformatw/getdateformatw_neg2:
+================================================
+Currently the only calendars that are supported are CAL_GREGORIAN
+and CAL_GREGORIAN_US.  The GetDateFormatW function will only be 
+called when the calendar is CAL_TAIWAN. Since this calendar is not
+currently supported in this release of the PAL, the GetDateFormatW
+function is not implemented except to return an error. This test
+will be useful when full calendar support is implemented.
+
+
+pal_specific/pal_get_stdin/test1 :
+=======================================
+This test case should be run manually.  Requires user input.
+
+
+threading/setconsolectrlhandler/test1
+threading/setconsolectrlhandler/test2
+threading/setconsolectrlhandler/test3
+threading/setconsolectrlhandler/test4
+=======================================
+These tests cases should be run manually.  Requires user input.
+
+threading/getprocesstimes/test1
+=======================================
+According to rotor_pal.doc, GetProcessTimes() should be supported for the current 
+process only. I've removed this test because it tests GetProcessTimes() with 
+invalid process handle value.
+
+threading/getthreadcontext/test1,1
+=======================================
+According to rotor_pal.doc, when GetThreadContext is call for a thread within 
+the same process, it could only be called for te current thread. I've removed
+this test, because it tests GetThreadContext() with a non current thread handle 
+belong the current procees.
+
+loader/loadlibrarya/test4
+loader/loadlibraryw/test4
+=======================================
+PAL BSD should not append the .so extension in LoadLibrary if the extension is 
+omitted.
+file_io/deletefilea/test3
+file_io/deletefilew/test3
+=======================================
+No code in Rotor depends on DeleteFile[A/W] failing on readonly files so we 
+don't need to exactly emulate this feature of the Win32 filesystems on FreeBSD.
+
+filemapping_memmgt\MapViewOfFile\test1
+=======================================
+Refer this github issue https://github.com/dotnet/coreclr/issues/5176

+
+
+===========================================================================
+
+1.  ENVIRONMENT SETUP
+~~~~~~~~~~~~~~~~~~~~~
+
+Within a Rotor build window (env.sh/env.csh/env.bat), no additional
+configuration needs to be done.
+
+
+2. RUNNING THE SUITES
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Run %ROTOR_DIR%\tests\pvtrun.pl to launch the test suites.  It will
+display information about each test as it runs, then report a
+summary of the results upon completion.
+
+The results are logged to %ROTOR_DIR%\tests\pvtResults.log.
+
+
+3. ENVIRONMENT VARIABLES AND AUTOMATED TESTING SPECIFICS
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+    
+3.1 PAL_DISABLE_MESSAGEBOX
+
+For automated testing on the WIN32 PAL, the following environment
+variable is useful to prevent pop-up message boxes from interupting the
+execution of the MessageBoxW test cases:
+
+set PAL_DISABLE_MESSAGEBOX=1  
+
+
+3.2 Other Notes
+
+See notes in section 4 on the following test cases if running automated tests:
+
+     Miscellaneous: messageboxw/test(1,2)
+     Threading: setconsolectrlhandler/test(3,4)
+
+
+4. ADDITIONAL NOTES ON TESTING/SPECIFIC TEST CASE ISSUES
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+C Runtime: _fdopen testing issues
+
+There is a very specific manner in which _fdopen has been documented to work,
+this will determine how the function will be tested.
+
+_fdopen takes a parameter of a c run-time file handle, to open a stream to the
+file. This file handle can only be returned from the _open_osfhandle function.
+The Rotor documentation states that _open_osfhandle will only return a 
+READ-ONLY file handle, from an operating-system file handle returned from
+CreatePipe().
+
+With these restrictions _fdopen will only be tested with a mode of read(r).
+The other modes are not possible to test. _open_osfhandle returns an error
+when attempting to open a write pipe handle in a mode of read-only. As well,
+it is not possible to read and write to the same handle that is returned from
+CreatePipe().
+
+The modes that will not be tested are as follows:
+
+    "w" -  Opens an empty file for writing. 
+    "a" -  Opens for writing at the end of the file (appending).
+    "r+" - Opens for both reading and writing.
+    "w+" - Opens an empty file for both reading and writing.
+    "a+" - Opens for reading and appending.
+
+
+
+File_IO: getfiletime/test5
+
+This test case is NTFS specific.
+
+
+File_IO: getfilesize/test1, getfilesizeex/test1 setfilepointer/test(5,6,7)
+
+These tests cases create a large number of temporary files which require  
+ample disk space.  On systems with less than 6Gb free disk space expect 
+these test cases to fail.
+
+
+File_IO: gettempfilename(a,w)/test2
+
+These test cases take longer than 60 seconds to run.  Currently, the Test 
+Harness will timeout any test case that exceeds 60 seconds.
+
+
+File_IO: setfileattributesa/test(1,4), SetFileAttributesW/test(1,4)
+
+These test cases ensure restricted file permissions are respected.  Administrators 
+or super users (root) are not affected by file permissions and, as a result, these
+test cases will fail for such users.
+
+
+Miscellaneous: messageboxw/test(1,2)
+
+Setting PAL_MESSAGEBOX_DISABLE=1 for these test cases prevents message box pop
+ups that occur during the tests' execution on Windows.  For automated testing
+where user interaction is not desired/possible, setting this environment 
+variable will prevent a pause in the automated test run.
+
+
+ic: pal_get_stdin/test1, pal_get_stdout/test1, pal_get_stderr/test1
+
+These test cases should be manually inspected to ensure the information being returned
+is correct.  The pal_get_stdin test case requires user input.  The pal_get_stdout and 
+pal_get_stderr test cases do not require user input, but their output should be inspected 
+to verify that correct messages are being displayed.
+
+
+Threading: setconsolectrlhandler/test(3,4)
+
+These test cases require user response in order to produce a meaningful results.
+For automated testing, this test case is disabled.

+**          test will write and read from the pipe comparing 
+**          the results.

+Description
+= Tests the PAL implementation of the fdopen function. 
+= This will test fdopen in r (read) mode. This test 
+= creates and opens a test pipe, to write and read 
+= from. fdopen requires a file handle(int), therefore
+= _open_osfhandle is used to get that handle. 
+= _open_osfhandle is only used with CreatePipe. The 
+= test will write and read from the pipe comparing 
+= the results.
+= As a secondary test, _close is tested since it needs
+= the handle returned by _open_osfhandle. The handle is
+= closed, then a read is attempted on the handle which 
+= should fail.

+= Take two strings and compare them, giving different lengths. 
+= Comparing str1 and str2 with str2 length, should return <0
+= Comparing str2 and str1 with str2 length, should return >0
+= Comparing str1 and str2 with str1 lenght, should return 0
+= Bring in str3, which has a capital, but this function is doing a lower
+= case compare.  Just ensure that two strings which differ only by capitals
+= return 0.

+To compile: 
+
+1) create a dat file (say object_management.dat) with contents:
+

+PAL,Composite,palsuite\composite\object_management\event\shared,event=main.c event.c,<SUPPORTEXE>,<TESTLANGCPP>,<COMPILEONLY>
+
+
+2) perl rrunmod.pl -r object_management.dat
+
+
+To execute:
+For each of the test cases, 
+main  [PROCESS_COUNT]  [THREAD_COUNT] [REPEAT_COUNT]
+
+
+Output:
+The performance numbers will be in <process_logical_id>_[event|semaphore|mutex].txt 
+(will be at palsuite\composite\object_management\[mutex|event|semaphore]\[shared|nonshared]\obj[r|c|d] directory if u use rrunmod.pl)
+
+So if process_count is 3, you will have files 0_mutex.txt, 1_mutex.txt and so on…
+
+For each process txt file created, 
+each row represents a thread data (process id, number of failures, number of pass,  total number of repeated operations and an integer that will be used to identify a run 
+(currently zero)).

+** Source: criticalsection.c
+**
+** Purpose: Test Critical Section Reengineering PAL Effort 
+**
+** PseudoCode:  
+	Preparation:
+		Create PROCESS_COUNT processes.
+		In each process create a Critical Section
+
+	Test:
+		Create THREAD_COUNT threads.
+		In a loop repeated REPEAT_COUNT times:
+			Enter Critical Section 
+				Do Work
+			Leave Critical Section 
+		The main thread waits for all of the created threads to exit (WFMO wait all on the created thread handles) and call DeleteCriticalSection
+
+	Parameters:
+		PROCESS_COUNT: Number of processes
+		THREAD_COUNT: Number of threads in each process
+		REPEAT_COUNT: The number of times to execute the loop..
+	
+	Statistics Captured:
+		Total elapsed time
+		MTBF
+
+     Scenario:
+     			Single Process with Multiple threads.  Main thread creates critical section.  
+     			All other threads call EnterCriticalSection.   When thread enters critical section 
+     			it does some work and leaves critical section.  
+     			
+** Dependencies: 
+			CreateThread
+**	              InitializeCriticalSection
+**    	       EnterCriticalSection
+**           	LeaveCriticalSection
+**               	DeleteCriticalSection
+**              	WaitForSingleObject

+By Patricia Reaney 
+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+** 	Source: \composite\threading\threadsuspension\threadsuspension.c
+**
+** 	Purpose: To verify Thread Suspension Reegneering effort for this milestone 
+
+	PsedoCode:
+
+		Preparation:
+		Create PROCESS_COUNT processes.
+		Test:
+			Create Worker Thread 
+				Start Reading and writing to a File
+			
+			Create Worker Thread
+				In an infinite loop do the following 
+					Enter Critical Section
+		 				Increment Counter
+					Leave Critical Section 
+			
+			Create Worker Thread
+				Allocate Memory and Free Memory
+			
+			Create Worker Thread
+				In a tight loop add numbers
+			
+			In a loop repeated REPEAT_COUNT times
+
+				Create Thread 
+				
+					Suspend all worker threads
+					Resume all worker threads
+
+			At the end of the loop call PAL_Shutdown
+
+		Parameters:
+			PROCESS_COUNT: Number of processes
+			WORKER_THREAD_MULTIPLIER_COUNT: Number of instances of worker threads in each process
+			REPEAT_COUNT: The number of times to execute the loop.
+
+		Statistics Captured:
+			Total elapsed time
+			MTBF
+
+
+	Scenario:
+**    
+		One thread suspends all remaining threads which are in the middle of doing some work and resume all threads
+		Thread 1:  Reading and Writing File
+		Thread 2:  Enter and Leave Critical Section
+		Thread 3:  Allocating chunks of memory
+		Thread 4:  Perform Unsafe Operation (printf, malloc)
+		Thread 5:  Suspends Thread 1 to Thread 4 and resumes them

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense blackasdf dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again. 
+
+The next transit will occur in 2012 when it will be visible from parts of Asia and the Pacific but not Europe.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said. 
+
+Internet sites will be covering the transit and observatories around the world have organized viewings. 
+
+"Mainly Western Europe could see some high cloud that might prevent people from seeing it," said a spokesman for Britain's Meteorological Office. "The rest of Europe shouldn't be too bad. It should be fine." 
+
+German astronomer Johannes Kepler first predicted a transit of Venus in 1627 but he died before he could witness one. English astronomer Jeremiah Horrocks first observed it in 1639. 
+
+The transit occurs four times in every 243 years. There are two December transits, eight years apart, and then 121.5 years later there are two June transits, also eight years apart. After another 105.5 years the cycle begins again.

+LONDON (Reuters) - Europe, Africa and the Middle East are the best vantage points to see the first transit of Venus across the sun in more than a century on Tuesday, scientists said. 
+
+Mostly clear skies are forecast in many parts of the three regions, but people were urged to be careful if they watch the rare event when it begins at 1:19 a.m. EDT because it could cause blindness. Views will be restricted from Asia and the Americas. 
+
+Unlike a solar eclipse by the moon that is over in two or three minutes, Venus's transit -- which last occurred in 1882 -- will go on for six hours. 
+
+The planet will appear as an intense black dot on the solar disc. 
+
+Most of the sun will be visible as Venus crosses to the right from the bottom left side of the solar disc. Venus will be 26.7 million miles from earth. 
+
+"Venus will be about 1/30 the size of the diameter of the sun, but it will be much darker and more intense than sunspots," said Dr Robert Walsh, of the University of Central Lancashire's Center for Astrophysics in northern England. 
+
+Scientists recommend some form of indirect projection as the safest way to observe the phenomenon. 
+
+"Never ever look directly at the sun with the naked eye or any sort of optical equipment -- telescope, binoculars or even digital camera," said Walsh. 
+
+"Even if you glance at the sun for a short period of time you can damage your eye and lose some of your sight," he said.

+/*============================================================
+**
+** 	Source: \composite\threading\threadsuspension\threadsuspension.c
+**
+** 	Purpose: To verify Thread Suspension Reegneering effort for this milestone 
+
+	PsedoCode:
+
+		Preparation:
+		Create PROCESS_COUNT processes.
+		Test:
+			Create Worker Thread 
+				Start Reading and writing to a File
+			
+			Create Worker Thread
+				In an infinite loop do the following 
+					Enter Critical Section
+		 				Increment Counter
+					Leave Critical Section 
+			
+			Create Worker Thread
+				Allocate Memory and Free Memory
+			
+			Create Worker Thread
+				In a tight loop add numbers
+			
+			In a loop repeated REPEAT_COUNT times
+
+				Create Thread 
+				
+					Suspend all worker threads
+					Resume all worker threads
+
+			At the end of the loop call PAL_Shutdown
+
+		Parameters:
+			PROCESS_COUNT: Number of processes
+			WORKER_THREAD_MULTIPLIER_COUNT: Number of instances of worker threads in each process
+			REPEAT_COUNT: The number of times to execute the loop.
+
+		Statistics Captured:
+			Total elapsed time
+			MTBF
+
+
+	Scenario:
+**    
+		One thread suspends all remaining threads which are in the middle of doing some work and resume all threads
+		Thread 1:  Reading and Writing File
+		Thread 2:  Enter and Leave Critical Section
+		Thread 3:  Allocating chunks of memory
+		Thread 4:  Perform Unsafe Operation (printf, malloc)
+		Thread 5:  Suspends Thread 1 to Thread 4 and resumes them

+Output:
+The performance numbers will be in <process_logical_id>_wfmo.txt 
+(will be at palsuite\composite\wfmo\obj[r|c|d] directory if u use rrunmod.pl)
+
+So if process_count is 3, you will have files 0_wfmo.txt, 1_wfmo.txt and so on…
+
+For each process txt file created, 
+each row represents a thread data (process id, number of failures, number of pass,  total number of repeated operations and an integer that will be used to identify a run 
+(currently zero)).

+**          consideration.  The first filter returns EXCEPTION_CONTINUE_SEARCH
+**          so the second can run and return EXCEPTION_EXECUTE_HANDLER.  The 
+**          initial exception handler should be skipped, and the second 
+**          executed

+Description
+= Tests the PAL implementation of the PAL_FINALLY in the presence
+= of a call stack. An exception is forced and passed to two nested
+= exception filters for consideration.  The first filter returns
+= EXCEPTION_CONTINUE_SEARCH so the second can run and return
+= EXCEPTION_EXECUTE_HANDLER.  The initial exception handler should
+= be skipped, and the second executed, and all the PAL_FINALLY
+= blocks handled.

+= Test the number of files that can be created. Since 
+= GetTempFileNameA only handles 8.3 file names, the test
+= attempts to create more than the maximum temp files possible
+= with a 3 character prefix. Since this test takes so long, it
+= is not to be included in the standard test harness.
+= This test will also need more than 4.07 GB free disk space.

+//lpPath 
+//[in] Pointer to a null-terminated string that specifies the path to be searched for the file. If this parameter is NULL, the function searches for a matching file in the following directories in the following sequence:

+//The Windows directory. Use the GetWindowsDirectory function to get the path of this directory. 
+//The directories that are listed in the PATH environment variable. 
+
+//lpFileName 
+//[in] Pointer to a null-terminated string that specifies the name of the file to search for. 
+
+//lpExtension 
+//[in] Pointer to a null-terminated string that specifies an extension to be added to the file name when searching for the file. The first character of the file name extension must be a period (.). The extension is added only if the specified file name does not end with an extension. 
+//If a file name extension is not required or if the file name contains an extension, this parameter can be NULL.
+//
+//nBufferLength

+
+//lpBuffer 
+//[out] Pointer to the buffer that receives the path and file name of the file found. 
+
+//lpFilePart 
+//[out] Pointer to the variable that receives the address (within lpBuffer) of the last component of the valid path and file name, which is the address of the character immediately following the final backslash (\) in the path. 
+
+//Return Values
+//If the function succeeds, the value returned is the length, in TCHARs, of the string copied to the buffer, not including the terminating null character. If the return value is greater than nBufferLength, the value returned is the size of the buffer required to hold the path.

+Description
+= Tests the PAL implementation of the FreeLibraryAndExitThread
+= function. When run, FreeLibraryAndExitThread will exit the 
+= process that it is called within, therefore we create a
+= thread to run the API. Then we test for the existance of the
+= thread and access to the library.

+Description
+= Have two processes obtain a lock on a single file, but in different
+= regions of the file.  Use Read/Write to ensure the locks are respected.
+= This requires some IPC, which is done here with a crude busy wait on a 
+= file (waiting for the file size to change) to avoid too many more
+= dependencies.

+/*============================================================
+**
+** Source:  CreateMutexA_ReleaseMutex/test1/CreateMutexA.c
+**
+** Purpose: This test case tests whether a Mutex object created
+**          with CreateMutex really works by mutually excluding
+**          threads from accessing a data structure at the same
+**          time.  Here we have a buffer that can be filled or
+**          emptied, we use a Mutex object to ensure that one
+**          operation cannot be started until the other is
+**          finished.  If one operation detects that the other
+**          has not finished, it fails.  There is a Producer
+**          thread which will try to fill the buffer 25 times,
+**          and a consumer thread which try to empty the buffer
+**          25 times.  If either the fill or empty operations
+**          fails because the Mutex failed to mutually exclude
+**          them, the corresponding thread will set an error
+**          flag and return.  This will cause the test case to
+**          fail.
+**
+**          To increase the probability of identifying problems,
+**          the Fill opeartion has been slowed down with a call
+**          to Sleep.  This ensures that one operation will try
+**          to access the shared buffer while the other is in
+**          progress.
+**
+**          NOTE: this test case also serves as a test case for
+**          WaitForSingleObject.

+Name = Positive Test for CreateMutexA and ReleaseMutex 
+TYPE = DEFAULT
+EXE1 = createmutexa
+Description 
+= This test cases test whether a Mutex object created
+= with CreateMutexA really works by mutually excluding
+= threads from accessing a data structure at the same
+= time.  Here we have a buffer that can be filled or
+= emptied, we use a Mutex object to ensure that one
+= operation cannot be started until the other is
+= finished.  If one operation detects that the other
+= has not finished, it fails.  There is a Producer
+= thread which will try to fill the buffer 25 times,
+= and a consumer thread which try to empty the buffer
+= 25 times.  If either the fill or empty operations
+= fails because the Mutex failed to mutually exclude
+= then, the corresponding thread will set an error
+= flag and return.  This will cause the test case to
+= fail.
+= To increase the probability of identifying problems,
+= the Fill opeartion has been slowed dowm with a call
+= to Sleep.  This ensures that one operation will try
+= to access the shared buffer while the other is in
+= progress.
+= NOTE: this test case also serves as a test case for
+= WaitForSingleObject.

+/*============================================================
+**
+** Source: CreateMutexA_ReleaseMutex/test2/CreateMutexA.c
+**
+** Purpose: This test case tests the following things
+**          - Creation of named Mutexes
+**          - Creating multiple handles to a single named Mutex
+**          - Ensuring that these handles work interchangeably
+**          - Setting bInitialOwnerFlag to TRUE will cause the
+**            initial call to a Wait function on the same Mutex
+**            to actually wait.
+**          - Waiting on a Mutex that a thread already owns does
+**            not block.
+**          - Create Named mutex with empty string ("")
+**          - Create Named mutex with string of MAX_LONGPATH length
+**          - Calling RelaseMutex with invalid Mutex handles and
+**            valid but unowned Mutexes.
+**
+** Dependencies: CreateThread
+**               ReleaseMutex
+**               WaitForSingleObject
+**               CloseHandle

+**
+** Source:  CreateMutexW_ReleaseMutex/test1/CreateMutexW.c
+**
+** Purpose: This test case tests whether a Mutex object created
+**          with CreateMutex really works by mutually excluding
+**          threads from accessing a data structure at the same
+**          time.  Here we have a buffer that can be filled or
+**          emptied, we use a Mutex object to ensure that one
+**          operation cannot be started until the other is
+**          finished.  If one operation detects that the other
+**          has not finished, it fails.  There is a Producer
+**          thread which will try to fill the buffer 25 times,
+**          and a consumer thread which try to empty the buffer
+**          25 times.  If either the fill or empty operations
+**          fails because the Mutex failed to mutually exclude
+**          them, the corresponding thread will set an error
+**          flag and return.  This will cause the test case to
+**          fail.
+**
+**          To increase the probability of identifying problems,
+**          the Fill opeartion has been slowed dowm with a call
+**          to Sleep.  This ensures that one operation will try
+**          to access the shared buffer while the other is in
+**          progress.
+**
+**          NOTE: this test case also serves as a test case for
+**          WaitForSingleObject.

+Description 
+= This test case tests the following things
+=    - Creation of named Mutexes
+=    - Creating multiple handles to a single named Mutex
+=    - Ensuring that these handles work interchangeably
+=    - Setting bInitialOwnerFlag to TRUE will cause the
+=      initial call to a Wait function on the same Mutex
+=      to actually wait.
+=    - Waiting on a Mutex that a thread already owns should
+=      not block.
+=    - Create Named mutex with empty string ("")
+=    - Create Named mutex with string of MAX_PATH length
+=    - Calling RelaseMutex with invalid Mutex handles and
+=      valid but unowned Mutexes.

+= Test the CreateProcessA function.  The test executes the childprocess 
+= program.  The childprocess program launches and writes a const char string

+= and then reads the string from the childdata file.  If the string in the 
+= file matches it's copy of the const char string, then the test succeeds.

+Name = Positive Test for CreateProcessW
+TYPE = DEFAULT
+EXE1 = parentprocess
+EXE2 = childprocess
+Description 
+= Test the CreateProcessW function.  The test executes the childprocess 
+= program.  The childprocess program launches and writes a const char string
+= to a file childdata.  The parent waits for the completion of childprocess
+= and then reads the string from the childdata file.  If the string in the 
+= file matches it's copy of the const char string, then the test succeeds.

+= Implementation of Producer / Consumer IPC problem using CreateSemaphoreA
+= and ReleaseSemaphore functions.  This test case exercises CreateSemaphoreA
+= , ReleaseSemaphore, CreateThread and WaitForSingleObject functions.  
+= Since there is no way to currently create "pseudo" random events in the

+= test case is designed to starve the consumer and have the producer fill
+= the buffer.

+Description 
+= Implementation of Producer / Consumer IPC problem using CreateSemaphoreA
+= and ReleaseSemaphore functions.  This test case exercises CreateSemaphoreA
+= , ReleaseSemaphore, CreateThread and WaitForSingleObject functions.  
+= Since there is no way to currently create "pseudo" random events in the 
+= pal, this example does not behave as classic bounded buffers would.  This
+= test case is designed to starve the producer and have the consumer fill
+= the buffer.

+Description
+= Test attributes of CreateSemaphoreW and ReleaseSemaphore.  
+= Insure for CreateSemaphore that lInitialCount and lMaximumCount
+= constraints are respected.  Validate that CreateSemaphore rejects 
+= conditions where, initial count and / or maximum count are negative 
+= and conditions where the initial count is greater than the maximum 
+= count.  For ReleaseSemaphore validate that lpPreviousCount gets set
+= to the previous semaphore count and lpPreviousCount can be NULL.
+= Also establish ReleaseSemaphore fails when called in a semaphore 
+= with count equal to lMaximumCount.

+= Implementation of Producer / Consumer IPC problem using the 
+= "CriticalSection" functions to provide a mutual exclusion mechanism.
+= This test case exercises InitializeCriticalSection, EnterCriticalSection,
+= LeaveCriticalSection, DeleteCriticalSection, and WaitForSingleObject 
+= functions.  
+= This case doesn't work with more than one producer and one consumer.  
+= The producer thread and consumer thread each take turns blocking on 
+= the CriticalSection object and do not have any other synchronization 
+= mechanisms.  This prevents adding producers or consumers as there are
+= no mechanisms to block them once the buffer is full.

+Description 
+= Test that we are able to nest critical section calls.  
+= The initial thread makes a call to EnterCriticalSection once, 
+= blocking on a CRITICAL_SECTION object and creates a new thread.  
+= The newly created thread blocks on the same CRITICAL_SECTION object.
+= The first thread now makes a call to LeaveCriticalSection.
+= Test to see that the new thread doesn't get unblocked.

+** Source:      CriticalSectionFunctions/test3/test3.c
+**
+** Purpose:     Create two threads to exercise TryEnterCriticalSection
+**              and EnterCriticalSection.  TryEnterCriticalSection acquires 
+**              and holds a CRITICAL_SECTION object.  Another call to 
+**              TryEnterCriticalSection is made from a different thread, at 
+**              this time, to establish a call to TryEnterCriticalSection
+**              will return immediatly and to establish 
+**              TryEnterCriticalSection returns the proper value when it
+**              attempts to lock a CRITICAL_SECTION that is already owned 
+**              by another thread.  The CRITICAL_SECTION object is then 
+**              released and held by a call to EnterCriticalSection.  A new 
+**              thread is invoked and attempts to acquire the held 
+**              CRITICAL_SECTION with a call to TryEnterCriticalSection.  
+**              TryEnterCriticalSection returns immediatly and returns
+**              with the value that states the CRITICAL_SECTION object is 
+**              held by another thread.  This establishes 
+**              TryEnterCriticalSection behaves the same way with 
+**              CriticalSections locked by TryEnterCriticalSection and 
+**              EnterCriticalSection.

+Description 
+= Create two threads to exercise TryEnterCriticalSection
+= and EnterCriticalSection.  TryEnterCriticalSection acquires 
+= and holds a CRITICAL_SECTION object.  Another call to 
+= TryEnterCriticalSection is made from a different thread, at 
+= this time, to establish a call to TryEnterCriticalSection
+= will return immediatly and to establish 
+= TryEnterCriticalSection returns the proper value when it
+= attempts to lock a CRITICAL_SECTION that is already owned 
+= by another thread.  The CRITICAL_SECTION object is then 
+= released and held by a call to EnterCriticalSection.  A new 
+= thread is invoked and attempts to acquire the held 
+= CRITICAL_SECTION with a call to TryEnterCriticalSection.  
+= TryEnterCriticalSection returns immediatly and returns
+= with the value that states the CRITICAL_SECTION object is 
+= held by another thread.  This establishes 
+= TryEnterCriticalSection behaves the same way with 
+= CriticalSections locked by TryEnterCriticalSection and 
+= EnterCriticalSection.

+** Source: criticalsectionfunctions/test4/test4.c
+** 
+** Purpose: Test to see if threads blocked on a CRITICAL_SECTION object will 
+** be released in an orderly manner.  This case looks at the following
+** scenario.  If one thread owns a CRITICAL_SECTION object and two threads 
+** block in EnterCriticalSection, trying to hold the already owned 
+** CRITICAL_SECTION object, when the first thread releases the CRITICAL_SECTION
+** object, will one and only one of the waiters get unblocked?
+**
+** Dependencies: CreateThread
+**               InitializeCriticalSection
+**               EnterCriticalSection
+**               LeaveCriticalSection
+**               DeleteCriticalSection
+**               Sleep

+Description 
+= Test to see if threads blocked on a CRITICAL_SECTION object will 
+= be released in an orderly manner.  This case looks at the following
+= scenario.  If one thread owns a CRITICAL_SECTION object and two threads 
+= block in EnterCriticalSection, trying to hold the already owned 
+= CRITICAL_SECTION object, when the first thread releases the CRITICAL_SECTION
+= object, will one and only one of the waiters get unblocked?

+Description
+= Test to ensure proper operation of the DuplicateHandle API.
+= The test launches a trivial child process, then opens
+= a handle to it using OpenProcess. It then duplicates that
+= handle and uses it to wait for the child process to terminate,
+= and then checks the exit code of the child process in order to
+= verify that it was in fact a handle to the correct= process. The test tries to duplicate the handle again after
+= the process has been closed, to verify that failure ensues.

+Description
+= Tests the PAL implementation of the DuplicateHandle function.
+= This test duplication of a Mutex handle. The test will comprise
+= of creating a Mutex and its duplicate and create a thread that will
+= get ownership. Another thread will be create that will attempt to 
+= get ownership of the duplicate Mutex, this will fail, since the 
+= Mutex is owned by another thread. The Mutex will be released and 
+= then the thread will attempt to get ownership of the duplicate
+= Mutex, this will succeed.

+= Tests the PAL implementation of the DuplicateHandle function,
+= with a handle from GetCurrentProcess. The test will create a 
+= process, duplicate it, then using ReadProcessMemory will
+= read from the memory location of the CreateProcess process
+= memory and the DuplicateHandle process memory. If the 
+= duplication is correct the memory will be the same for both.

+= via ExitThread, the process exits with the proper return
+= code.

+Name = Positive test for OpenEventW
+TYPE = DEFAULT

+Description 
+= Test to ensure proper operation of the OpenEventW()
+= API by creating a new named event with CreateEventA()
+= and verifying that it can be opened with OpenEventW().
+= It should be possible to use the event handles
+= interchangeably, we test by setting the event with the
+= original handle and waiting on it with the new one,
+= then resetting it with the new one and waiting
+= on it with the original one.

+Description 
+= Test to ensure proper operation of the OpenProcess API.
+= The test launches a trivial child process, then opens
+= a handle to it using OpenProcess. It uses that handle
+= to wait for the child process to terminate, and then
+= checks the exit code of the child process in order to
+= verify that it was in fact a handle to the correct
+= process.

+= Test to ensure proper operation of the QueueUserAPC()
+= API by trying to queue and activate APC functions on

+= it.  We're verifying the following behavior:
+=
+= "If an application queues an APC before the thread begins
+= running, the thread begins by calling the APC function.
+= After the thread calls an APC function, it calls the APC
+= functions for all APCs in its APC queue."
