     int
     pthread_mutex_init(pthread_mutex_t *restrict mutex, const pthread_mutexattr_t *restrict attr);

     [EAGAIN]		The system temporarily lacks the resources to create another mutex.

     [EINVAL]		The value specified by attr is invalid.

     [ENOMEM]		The process cannot allocate enough memory to create another mutex.
