 *	Inter-Process-Communication (IPC) transport using shared memory (file
 *	mapping).  These are the client routines used by spawndrv.exe to
 *	connect back to the "exp_spawn" channel driver within the Expect
 *	extension.  This is bi-directional like sockets and namedpipes.  This
 *	works for ALL versions of windows.  This IPC method does not traverse
 *	a network and is only local to a single computer.
