2012-05-03 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. The pthread_mutex_init() function initializes the mutex referenced by mutex with attributes specified by attr.

The pthread_mutexattr_init() function initializes a mutex attribute object with the default settings for each attribute, as follows: 2021-02-27 You initialize a mutex by calling the pthread_mutex_init() function. The first parameter is the address of the mutex. If you need to initialize a mutex with non-default attributes, the second parameter can specify the address of an attribute object.

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 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。 LinuxThreads の実装はただ一つの属性 mutex kind だけに対応している。 2019-02-12 · A simple example for using pthread_cond_wait() and pthread_cond_signal() with mutexes and conditional variables.

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 default type is “normal�.
