Per POSIX pthread_mutex_init(): "In cases where default mutex attributes are appropriate, the macro PTHREAD_MUTEX_INITIALIZER can be used to initialize mutexes. The effect shall be equivalent to dynamic initialization by a call to pthread_mutex_init() with parameter attr specified as NULL , except that no error checks are performed."
2019-11-20 · If unsuccessful, pthread_mutex_init() returns -1. int pthread_mutex_lock(pthread_mutex_t *mutex) : Locks a mutex object, which identifies a mutex. If the mutex is already locked by another thread, the thread waits for the mutex to become available. Per POSIX pthread_mutex_init(): "In cases where default mutex attributes are appropriate, the macro PTHREAD_MUTEX_INITIALIZER can be used to initialize mutexes. The effect shall be equivalent to dynamic initialization by a call to pthread_mutex_init() with parameter attr specified as NULL , except that no error checks are performed." mutex_init(struct mutex *lock); Argument: struct mutex *lock – the mutex to be initialized.
_M_. A pointer to a caller-supplied NDIS_MUTEX-type mutex object. Example. POSIX thread library provides implementation of the mutex primitive, used for the mutual exclusion.
WL#10314: InnoDB: Lock-sys optimization: sharded lock_sys mutex. Affects: Server-8.0 — Status: Complete. Description; Requirements; Dependent Tasks; High
Upon successful initialization, the state of the mutex becomes initialized and unlocked. 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.
Använd metoden tryLock() för att ta över ägarskapet för mutex-objektet, om det är tillgängligt. Använd metoden lock() för att pausa den aktuella arbetarens
After initialization, the mutex is in an unlocked state. pthread_mutex_init initializes the mutex object pointed to by mutex according to the mutex attributes specified in mutexattr. If mutexattr is NULL , default attributes are used instead. The LinuxThreads implementation supports only one mutex attributes, the mutex kind , which is either ``fast'', ``recursive'', or ``error checking''. C++ (Cpp) MUTEX_INIT - 30 examples found.
The main functions for using a mutex are cyg_mutex_lock and cyg_mutex
pthread_mutex_init initializes the mutex object pointed to by mutex according to the mutex attributes specified in mutexattr. If mutexattr is NULL , default attributes are used instead. The type of a mutex determines whether it can be locked again by a thread that already owns it. Description: The pthread_mutex_init () function initializes the given mutex object, using the attributes specified by the mutex attributes object attr. If attr is NULL, then the mutex is initialized with the default attributes (see pthread_mutexattr_init () ).
