14 Acquire the lock on mutex. If the mutex is already locked by another
15 thread, the call will block until the mutex becomes available and
16 locked.

18 If the mutex is already locked by the calling thread, then the behavā
19 iour depends on whether the mutex was created with al_create_mutex(3)
20 or al_create_mutex_recursive(3). In the former case, the behaviour is
21 undefined; the most likely behaviour is deadlock. In the latter case,
22 the count in the mutex will be incremented and the call will return
23 immediately.
