In this situation, if mutex_init() is called on a previously initialized robust mutex, mutex_init() will not reinitialize the mutex and will return the error value EBUSY. Creates a mutex, referenced by mutex, with attributes specified by attr. If attr is NULL, the default mutex attribute (NONRECURSIVE) is used. Returned value. If successful, pthread_mutex_init() returns 0, and the state of the mutex becomes initialized and unlocked. The pthread_mutex_init() function shall initialize the mutex referenced by mutex with attributes specified by attr.

Mutex init

More Detailed Description. Mutex for thread synchronization.. Mutex Implementation Basics Data Structures and Encoding . A mutex_t contains basically a point, which can have one of the following values:. NULL, in case it is unlocked; MUTEX_LOCKED in case it is locked, but no other thread is waiting on it; A pointer to the head of single linked list of As mutex attribute object is opaque type, appropriate set and get functions are availables to manupulate mutex attributes.

Mutex init

type must have one of the following values: mtx_plain - a simple, non-recursive mutex is created. void g_mutex_init (GMutex *mutex); Initializes a GMutex so that it can be used. This function is useful to initialize a mutex that has been allocated on the stack, or as part of a larger structure. 1.

type must have one of the following values: mtx_plain - a simple, non-recursive mutex is created. mtx_timed - a non-recursive mutex, that supports timeout, is created. An implementation may cause pthread_mutex_destroy () to set the object referenced by mutex to an invalid value.
