This email sent to site_archiver@lists.apple.com We don't support unnamed POSIX semaphores, we don't support sem_getvalue(), and if you try you get a SIGSYS, which if you don't catch it, you're program exits. We also don't guarantee correct error semantics for the POSIX named semaphores we do have, since if we can't run the conformance tests because we don't support unnamed semaphores, we can't tell if the errors we return are correct or not. Is there a technical reason that Darwin doesn't support POSIX unnamed semaphores or it's just not a priority since they're not necessary? smime.p7s
