If the attribute object is modified later, the mutex's attributes are not affected. If attr is NULL, the mutex is initialized with default attributes, as specified for pthread_mutexattr_init(). 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() will not reinitialize the mutex and will return the error value EBUSY. 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.

Elixir Cross Referencer - Explore source code in your browser - Particularly useful for the Linux kernel and other low-level projects in C/C++ (bootloaders, C The pthread_mutex_init() function creates a new mutex, with attributes specified with attr. If attr is NULL, the default attributes are used. The macro PTHREAD_MUTEX_INITIALIZER can be used to initialize a mutex when the default a pthread_mutex_init (&mutex, &attr); Priority inheritance can be combined with any of the four types. However, it adds a large overhead to the implementation and so it does not make sense to combine it with the fast or adaptive types. Unexpected termination: the robust mutex.
