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 behaviour depends on whether the mutex was
       created with al_create_mutex(3alleg5) or al_create_mutex_recursive(3alleg5).  In the former case, the be‐
       haviour 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(3alleg5).

       We don’t yet have al_mutex_trylock.
