X-BeenThere: freebsd-current@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: Discussions about the use of FreeBSD-current List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 30 Jan 2004 13:58:08 -0000 Could anybody enlighten me, please? 1) What is current status of POSIX semaphores? Are they at the production quality? Are they better implemented than SYSV ones? 2) What is kernel option to turn them on? Why I don't find it in NOTES or GENERIC? The reason why I ever ask is that some ports try to sense POSIX semaphores at configure stage (looking for sem_init()) and then compiled program fails with "Unknown system call" diagnostic. -- Andrey Chernov | http://ache.pp.ru/
