Any thread or process interested in the robust lock can call mutex_init() to potentially initialize it, provided that all such callers of mutex_init() specify the same set of attribute flags. In this situation,
Any thread or process interested in the robust lock can call mutex_init() to potentially initialize it, provided that all such callers of mutex_init() specify the same set of attribute flags. In this situation, if mutex_init() is called on a previously initialized robust mutex, mutex_init...

locking it will return the current value and the locking process will continue execution immediately; the semaphore will be decremented upon locking. Releasing the lock will increment the semaphore again.
thread at a given time can have access to a common resource. When two or more threads executing in the server need to access the same resource, the threads compete against each other. The first thread to obtain a lock on the mutex causes the other threads to wait until the lock is ...

Just as with thelockstatement, aMutexcan be released only from the same thread that obtained it. A common use for a cross-processMutexis to ensure that only one instance of a program can run at a time. Here’s how it’s done: ...
A Mutex is like a C# lock, but it can work across multiple processes. In other words, Mutex can be computer-wide as well as application-wide. Acquiring and releasing an uncontended Mutex takes a few microseconds—about 50 times slower than a lock. ...

Their synchronization semantics are very different: mutexesallow serialization of access to a given resource i.e. multiple threads wait for a lock, one at a time and as previously said, the threadownsthe lock until it is done: onlythis particular thread can unlock it. ...
