+** Source: test1.c
+**
+** Purpose: Tests that FlushInstructionCache returns the correct value for a 
+**          number of different inputs.
+**
+**
+** Note :
+** For this function, what constitutes "invalid parameters" will depend entirely
+** on the platform; because of this we can't simply test values on Windows and 
+** then ask for the same results everywhere. Because of this, this test can 
+** ensure that the function succeeds for some "obviously" valid values, but 
+** can't make sure that it fails for invalid values.
