** Source: test1.c (CreatePipe)
**
** Purpose: Tests the PAL implementation of the CreatePipe function.
** This test will create two pipes, a read and a write. Once
** the pipes have been created, they will be tested by writing
** and then reading, then comparing the results.
**
** Depends: WriteFile
** ReadFile
** memcmp
** CloseHandle
