Since foo() is called in another process (the child process of the one that called fork()), you will have to somehow attach to the child process after the fork() call. I don't know if gdb has support for doing this automatically. I don't think it does, but you might be able to attach to it in another gdb session by having the child process sleep for a while shortly after the fork() call to give you enough time to look up the PID of the child process. > > Thanks in Advance. > Thierry. > -- Brian O'Shea boshea@ricochet.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
