** Source: createprocessw/test2/parentprocess.c
**
** Purpose: Test the following features of CreateProcessW:
** - Check to see if hProcess & hThread are set in
** return PROCESS_INFORMATION structure
** - Check to see if stdin, stdout, & stderr handles
** are used when STARTF_USESTDHANDLES is specified
** in STARUPINFO flags and bInheritHandles = TRUE
** - Check to see that proper arguments are passed to
** child process
**
** Dependencies: CreatePipe
** strcpy, strlen, strncmp, memset
** WaitForSingleObject
** WriteFile, ReadFile
** GetExitCodeProcess
**
