Re: [Mingw-users] cwait for multiple spawned processes

[Luke D. <cod...@ho...>]

You could use CreateProcess() and then WaitForMultipleObjects() to wait for
one of the processes to terminate (possibly with a zero timeout). Since the
value returned by spawn*() is apparently a process handle, you can probably
pass it to WaitForMultipleObjects() instead of using CreateProcess(). Once
you have determined that a process has finished, use GetExitCodeProcess() if
you need the exit status.

I don't know of anything like SIGCHLD that is provided by Windows, but
somebody else might.
