Their was an post on bugtraq a few days ago about this, it had a list with all system calls which are reentrant safe under OpenBSD. The paper was about signals, and is available at http://razor.bindview.com/publish/papers/signals.txt OpenBSD had a manpage wich lists all the function which should be be safe to call from a signal handler. It might be a nice place to start. You should only look at those from section 2 of course. http://www.openbsd.org/cgi-bin/man.cgi?query=sigaction Kurt ^ permalink raw reply [flat|nested] 2+ messages in thread
