-** Source: helper.c

-** Purpose: This helper process sets up a several blocks of memory,
-** then uses a file to tell its parent process where that memory is
-** So it can do a WriteProcessMemory on it. When the parent process is done
-** we check here that it was written properly.

- *

- * surrounding the '*pDest'[0..'lenDest'] region so that this function
