Subj : share a exclusive resource between the threads inside the different processes To : comp.programming.threads From : Hank Date : Wed Mar 23 2005 12:45 pm Hi, Is is possible to share a exclusive resource between the threads inside the different processes? For example: ( In linux platform with POSIX thread ) have 3 processes and each contain 3 threads , in other words there are 9 threads inside the different processes how these threads can access the resource synchronously? mutex? semaphore? locking file? or.......... .
