The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect shall be the same as passing the address of a default mutex attributes object. C++ (Cpp) MUTEX_INIT - 30 examples found. These are the top rated real world C++ (Cpp) examples of MUTEX_INIT extracted from open source projects.

Each time the owning thread acquires the mutex the lock count is incremented. The Unlock() -- Release the mutex. If other threads are waiting, then -- wake up the oldest one and give it the lock. -- Init() -- Each mutex must be initialized.
