For inter-process synchronization, a mutex needs to be allocated in memory shared between these processes. Since the memory for such a mutex must be allocated dynamically, the mutex needs to be explicitly initialized using mutex_init(). The mutex_init() function initializes the mutex referenced by mp with the type specified by type .

If attr is non-NULL, the attributes specified are used to initialize the mutex. If the attribute object is modified later, the mutex's attributes are not affected.

Mutex is a synchronization primitive that grants exclusive access to the shared resource to only one thread.

The object pointed to by mutex is set to an identifier of the newly created mutex. type must have one of the following values: mtx_plain - a simple, non-recursive mutex is created. mtx_timed - a non-recursive mutex, that supports timeout, is created. An implementation may cause pthread_mutex_destroy () to set the object referenced by mutex to an invalid value. A destroyed mutex object can be reinitialized using pthread_mutex_init (); the results of otherwise referencing the object after it has been destroyed are undefined. It shall be safe to destroy an initialized mutex that is unlocked.
