** 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
**
