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.

Synopsis: #include pthread_mutex_t mutex = PTHREAD_MUTEX_INITIALIZER; int pthread_mutex_init( pthread_mutex_t* mutex, const pthread_mutexattr_t* attr); Arguments: mutex A pointer to the pthread_mutex_t object that you want to initialize. attr NULL, or a pointer to a pthread_mutexattr_t object that specifies the attributes that you … pthread_mutex_init, pthread_mutex_lock, pthread_mutex_unlock. Notes. For speed, Pthreads-w32 never checks the thread ownership of non-robust mutexes of type PTHREAD_MUTEX_NORMAL (or PTHREAD_MUTEX_FAST_NP) when performing operations on the mutex. It is therefore possible for one thread to lock such a mutex and another to unlock it. pthread_mutex_init(3) NAME pthread_mutex_init - Initializes a mutex.

Upon successful initialization, the state of the mutex becomes initialized and unlocked. PTHREAD_MUTEX_INIT(3) BSD Library Functions Manual PTHREAD_MUTEX_INIT(3) NAME pthread_mutex_init-- create a mutex SYNOPSIS #include int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); DESCRIPTION The pthread_mutex_init() function creates a new mutex, with attributes specified with attr. Example.

I encountered an odd question about linux mutex lock, with Fedora 16 x64 as the development platform. Code: pthread_mutex_t lock; // in my

Passing NULL is equivalent to passing a mutex attribute object with all attributes set to their default values. NAME.

The mutex class is a synchronization primitive that can be used to protect shared data from being simultaneously accessed by multiple threads.. mutex offers exclusive, non-recursive ownership semantics:

Using pthread_mutex_lock() and pthread_mutex_unlock() Mutex locks are acquired and released. Se hela listan på baike.baidu.com pthread_mutex_t的初始化有两种方法，一种是使用函数pthread_mutex_init，使用结束需要调用函数pthread_mutex_destroy进行销毁，调用时mutex必须未上锁。 It shall be safe to destroy an initialized mutex that is unlocked. Attempting to destroy a locked mutex or a mutex that is referenced (for example, while pthread_mutex_init は mutex が指す mutex オブジェクトを、 mutexattr で指定された mutex 属性オブジェクトに従って初期化する。 mutexattr が NULL, ならば、デフォルトの属性がこのかわりに使われる。 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。 * Public interface - so don't trust the lock - initialize it first. */ int pthread_mutex_init (pthread_mutex_t *omutex, const pthread_mutexattr_t *attr) glibc / nptl / pthread_mutex_init.c Go to file Go to file T; Go to line L; Copy path Copy permalink . Cannot retrieve contributors at this time. 162 available, pthread_mutex_init should never have allowed the type to: be set. So it will get the default case for an invalid type.

Upon successful initialization, the state of the mutex becomes initialized and unlocked. PTHREAD_MUTEX_INIT(3) BSD Library Functions Manual PTHREAD_MUTEX_INIT(3) NAME pthread_mutex_init-- create a mutex SYNOPSIS #include int pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr); DESCRIPTION The pthread_mutex_init() function creates a new mutex, with attributes specified with attr. Example. 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.

The pthread_mutex_init() function may fail if: EINVAL Mutex attributes can be specified at mutex creation time, by passing a mutex attribute object as second argument to pthread_mutex_init(3). Passing NULL is equivalent to passing a mutex attribute object with all attributes set to their default values. Mutexes are used to protect shared data structures being concurrently accessed. If a mutex is destroyed while a thread is blocked waiting for that mutex, critical sections and shared data are no longer protected.

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.
