site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Hi all I am creating a semaphore using ftok, semget and then initializing. I want to change the maximum value of semaphore. I think the variable is semvmx and its value is around 32767 and I want to keep it is 3 in my case so please suggest me how to do it. -- Terry _______________________________________________ Do not post admin requests to the list.

The aggregate value is max 65535, but that assumes that you don't increment it more than 32767 total in a given process. Unfortunately, we can't change this without damaging binary and some source compatibility. This email sent to site_archiver@lists.apple.com
