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. When the mutex is no longer needed, it is destroyed by calling pthread_mutex_destroy(). The pthread_mutex_init() function initializes the mutex referenced by mutex with the attributes attr. If the parameter attr is NULL, the default mutex attributes are used. Refer to pthread_mutexattr_init(3T) for a list of default mutex attributes.

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 type of a mutex determines whether it can be locked again by a thread that already owns it. The default type is “normal�.

• A thread shouldn't lock if it is already the owner.

PTHREAD_MUTEX_INITIALIZER vs pthread_mutex_init & mutex

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。.

Pthread mutex init

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. 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.

Pthread mutex init

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. hidden_def (__pthread_mutex_init) 167: Generated on 2019-Mar-30 from project glibc revision glibc-2.29.9000-166-g656dd306d4 Powered by Code Browser 2.1 … 2018-01-01 pthread_mutex_init() Initialize mutex.
