Has anyone implemented a mutex with a timeout?
Has anyone implemented a mutex locking function on top of Solaris or POSIX threads with a timeout? The problem I’m trying to solve is if a thread is unable to obtain a mutex after a certain timeframe (say 30 seconds), then I want the thread to terminate and return an error. The Solaris and POSIX API’s only allow the user to check if a mutex can be obtained. Of course!
