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 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.

int mtx_init( mtx_t* mutex, int type ); (since C11) Creates a new mutex object with type. 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. void g_mutex_init (GMutex *mutex); Initializes a GMutex so that it can be used.

A mutex_t contains basically a point, which can have one of the following values:. NULL, in case it is unlocked; MUTEX_LOCKED in case it is locked, but no other thread is waiting on it; A pointer to the head of single linked list of As mutex attribute object is opaque type, appropriate set and get functions are availables to manupulate mutex attributes. pthread_mutex_init: To initialize mutex pthread_mutex_destroy : int uv_thread_create_ex (uv_thread_t* tid, const uv_thread_options_t* params, uv_thread_cb entry, void* arg) ¶. Like uv_thread_create(), but additionally specifies options for creating a new thread.. If UV_THREAD_HAS_STACK_SIZE is set, stack_size specifies a stack size for the new thread.0 indicates that the default value should be used, i.e. behaves as if the flag was not set. 1 day ago Unlike spinlocks, a process trying to acquire a mutex will suspend itself if it failes to acquire it.
