I am using boost 1.47 on linux/solaris(/hpux). Can you please tell me, how to find out the lock owner of a mutex (named_recursive_mutex) ? (in case i can't equire the lock within a timeout). In posix' pthread_mutex_t there is a int __owner; which holds the thread id (gettid()) But i can't find it in boost::interprocess. Ok. there might be different base implementations for mutex/threads/etc. But is there a "boost ID", that can be logged by application using boost which might be a linux/unix thread id, but maybe something else? - many thanks! best regards, Frank
Hi, Boost.Interprocess has no why to tell you this. "__owner" is not POSIX, but an implementation detail of the type pthread_mutex_t in your platforms. In those platforms, probably Boost.Interprocess builds a process-shared recursive mutex in shared memory (follow named_recursive_mutex constructor to see where it's built) of the type pthread_mutex_t. Maybe you can use the implementation details of your platform to obtain the ID. Best, Ion
