+** Source:  GetTempFileNameW.c (test 3)
+**
+** Purpose: Tests the PAL implementation of the GetTempFileNameW function.
+**          Checks the file attributes and ensures that getting a file name,
+**          deleting the file and getting another doesn't produce the same 
+**          as the just deleted file. Also checks the file size is 0.
+**
+** Depends on:
+**          GetFileAttributesW
+**          DeleteFileW
+**          CreateFileW
+**          GetFileSize
+**          CloseHandle
