wrong exitstatus returned?

[Frank de Bot]

Hi,

I have a perl script server which works with fork. But I got a problem
with executing commands from a child which handles a request. The
exitstatus $? is always -1 I've tried execute commands with system and
`command` but nothing matters.
What can be wrong?

Thanks in advanced,

Linux?
Win32?
Win32 with cygwin?

I found out that $? won't function if the SIGCHLD handler is set, which
it is. I've found a very rude way to solve this problem by adding the
exit status via another script in front of the stdout of command I want
to run.
But I don't realy like this method, any suggestion?

If you have a handler, use it. See "perldoc -f waitpid".
