Page 556 of the "Microsoft C 5.1 Optimizing Compiler User's Guide"
states that to obtain the exit code for an asynchronous spawned
process, you must call the wait or cwait function and specify the
process ID.

Wait, Cwait, and asynchronous spawns can only occur in protected mode.

The wait function suspends the calling process until any of the
caller's immediate child processes terminate. If all of the caller's
child processes have terminated before it calls the wait function, the
function returns immediately.

The cwait function suspends the calling process until the specified
child process terminates.

Compiler User's Guide" Update Pages 30 and 48.
