Results are undefined if pthread_mutexattr_init () is called specifying an already initialized attr attributes object. int pthread_mutex_destroy (pthread_mutex_t *mutex) : Deletes a mutex object, which identifies a mutex.

The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. available, pthread_mutex_init should never have allowed the type to: be set. So it will get the default case for an invalid type. */ # ifdef __NR_futex: case PTHREAD_MUTEX_PI_RECURSIVE_NP: case PTHREAD_MUTEX_PI_ERRORCHECK_NP: case PTHREAD_MUTEX_PI_NORMAL_NP: case PTHREAD_MUTEX_PI_ADAPTIVE_NP: case PTHREAD_MUTEX_PI_ROBUST_RECURSIVE_NP: 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. C Programming in Linux Tutorial using GCC compiler.

The pthread_mutex_init() function initializes the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect is the same as passing the address of a default mutex attributes object. Upon successful initialization, the state of the mutex becomes initialized and unlocked. The pthread_mutex_init() function initializes the mutex referenced by mutex with attributes specified by attr. If attr is NULL, the default mutex attributes are used; the effect is the same as passing the address of a default mutex attributes object. The pthread_mutex_init() function initializes the mutex referenced by mutex with attributes specified by attr.

It is recommended that you define and initialize the pthread_mutex_t objects in the same compile unit. 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. Upon successful initialization, the state of the mutex becomes initialized and unlocked. The pthread_mutex_init() function initializes a mutex with the specified attributes for use. 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.
