Very Computer

When I want to run new program(PROG) I should run fork() and run exec()
in child.

Parent before fork() can do a lot of checks for PROG (stat(), etc), but
exec() in child can be failed (no memory, etc).

In my propgram parent should know if call exec() in child was
successfull.

How can I do it ?

ps: please answer me also on my e-mail (a lot of messages in news groups
lost by my news server).

if you can't execute you program, simply terminate the child with exit(-1).
The parent should set a signal handler for sigchild so it can call wait()
(which avoids zombies by the way) to get the child's status.
