** Source: CreateProcessA/test1/parentprocess.c

** Purpose: Test to ensure CreateProcessA starts a new process. This test
** launches a child process, and examines a file written by the child.
** This process (the parent process) reads the file created by the child and
** compares the value the child wrote to the file. (a const char *)
**
** Dependencies: GetCurrentDirectory
** strlen
** WaitForSingleObject
** fopen
** fclose
** Fail
