+** 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
