Hello, is there a way to create process-shared mutexes in Red Hat Linux 7.* ? Currently, calling pthread_mutexattr_setpshared with PTHREAD_PROCESS_SHARED gives me ENOSYS. Is this going to change anytime soon? Is there *any* implementation for process-shared synchronization objects in the Linux kernel? Please CC me if responding to the list, as I'm on digest mode. Thanks! - Yuval "My opinions may change but not the fact that I am right."
