Thread Synchronization. The most important aspect of parallel programming is synchronization among the various parallel executing agents that access a common resource. Some access operations are conflicting and cannot be executed simulateneously. One common conflicting operations are: Reading by one thread and writing by another thread

Upon successful initialization, the state of the mutex becomes initialized and unlocked. 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()). After initialization, the mutex is in an unlocked state. 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 ()).

The new mutex may be used immediately for serializing critical resources. If attr is specified as NULL, all attributes are set to the default mutex attributes for the newly created mutex. With these declarations and initialization: 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. The pthread_mutex_init () function initializes the specified mutex.

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。. pthread_mutex_init () 函数是以动态方式创建互斥锁的，参数attr指定了新建互斥锁的属性。. 如果参数attr为空 ( NULL )，则使用默认的互斥锁属性，默认属性为快速互斥锁 。.

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.

If the parameter attr is NULL , the default mutex attributes are used.
