A simple way of implementing process-shared anonymous semaphores, using the kernel support, is to simply create a temporary semaphore, and (important part) store the pathname in the sem_t. Then, every semaphore operation becomes sem_open, kernel operation, sem_close, and destroy unlinks the temporary semaphore. This would be a poor-quality implementation, but it would work. A better implementation would not use a temporary semaphore at all. -GAWollman To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
