Q: wait for child, process its return value

[Nils Philippsen <nils wombat dialup fht-esslingen de>]

Hello,

For a program I write (simple GUI for a UUCP feed, at the moment just a
single button which will run sendmail -q, then uucico, then sendmail -q
again) I need to do something like this:

wait on the child process, while processing gtk+ events (here wait() will
not suffice) but after the child's death I need it's return value (and I
don't want to know, when a child is SIGSTOPped), so signal(SIGCHLD, ...)
won't suffice, too.

Has anybody a suggestion how to continue processing gtk+-events and having
the subsequently called program's return value?

Bye, Nils
