If the supplied extended pthread_mutex_t object is not in shared memory, pthread_mutex_init () will treat the object as a non-shared object, since it is not accessible to any other process. It is recommended that you define and initialize the pthread_mutex_t objects in the same compile unit.

Pthread mutex init

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. The dynamic way to do it (i.e., at run time) is to make a call to pthread_mutex_init () as follows: int rc = pthread_mutex_init (&lock, NULL); assert (rc == 0); // always check success! The first argument to this routine is the address of the lock itself, whereas the second is an optional set of attributes. C++ (Cpp) pthread_mutex_init_value - 21 examples found. These are the top rated real world C++ (Cpp) examples of pthread_mutex_init_value extracted from open source projects.

Pthread mutex init

POSIX thread library provides implementation of the mutex primitive, used for the mutual exclusion. Mutex is created using pthread_mutex_init, and destroyed using pthread_mutex_destroy. int pthread_mutex_init ( pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; l 函数作用:. 该函数用于C函数的多线程编程中,互斥锁的初始化。.

The LinuxThreads implementation supports only one mutex attributes, the mutex kind , which is either ``fast'', ``recursive'', or ``error checking''. 正常に実行された場合、pthread_mutex_init() は 0 を戻し、mutex は初期化され、アンロックされた状態になります。 正常に実行されなかった場合、pthread_mutex_init() は -1 を戻して、errno を次のいずれかの 値に設定します。 The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect shall be the same as passing the address of a default mutex attributes object.
