al_lock_mutex(3)					      al_lock_mutex(3)

NAME
       al_lock_mutex - Allegro 5 API

SYNOPSIS
	      #include <allegro5/allegro.h>

	      void al_lock_mutex(ALLEGRO_MUTEX *mutex)

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

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

SEE ALSO
       al_unlock_mutex(3).

       We don't yet have al_mutex_trylock.
