Subject: setitimer() and fork()
Date: Sun, 28 Jan 2001 15:46:38 +0100	[thread overview]
Message-ID: <20010128154637.A3193@ping.be> (raw)

I'm having a problem when I try to profile a program that
fork()'s. The problem is that it does count how many times I'm in
a function, but nothing seems to use any cpu time at all.

If I call setitmer(ITIMER_PROF, ...) again after the
fork, it works as expected.  fork() doesn't seem to copy the
timer(s). On other OS's, I don't seem to have to do this.

I'm having this problem with both 2.2, and 2.4.  I think it used
to work in older versions.

Is this a bug, or is this intentional?


Kurt
