The mutex_init() function initializes the mutex referenced by mp with the type specified by type . Upon successful initialization the state of the mutex becomes initialized and unlocked. The _OPEN_SYS_MUTEX_EXT feature switch can be optionally included. If the feature is set, then significantly larger pthread_mutex_t objects will be defined. The feature is used for the management of mutex and condition variables in shared memory. The pthread_mutex_init() function initializes a mutex with the specified attributes for use. The new mutex may be used immediately for serializing critical resources.

Mutex init

A mutex is initialized and then a lock is achieved by calling the following two functions : int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); int pthread_mutex_lock(pthread_mutex_t *mutex); 2018-06-23 mutex_init (mutex_t *mtx) Initialise a mutex structure. More void mutex_enter_blocking (mutex_t *mtx) Take ownership of a mutex. More bool mutex_try_enter (mutex_t *mtx, uint32_t *owner_out) Check to see if a mutex is available.

Initialize the mutex to unlocked state. It is not allowed to initialize an already locked mutex.

mutex offers exclusive, non-recursive ownership semantics: A calling thread owns a mutex from the time that it successfully calls either lock or try_lock until it calls unlock. /// A [`Mutex`] must first be initialised with a call to [`Mutex::init`] before it can be used. The /// [`mutex_init`] macro is provided to automatically assign a new lock class to a mutex instance. The pthread_mutex_init () function initializes the specified mutex. 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.

If successful, pthread_mutex_init() returns 0, and the state of the mutex becomes initialized and unlocked. The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr.
