According to the man pages, if 1 is EPERM. And from the POSIX Spec (see http://www.opengroup.org/onlinepubs/009695399/toc.htm): [EPERM] The mutex was not owned by the current thread at the time of the call. I suggest Butenhof's "Programming with POSIX Threads" book. -- DE _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
