NAME
       al_join_thread - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              void al_join_thread(ALLEGRO_THREAD *thread, void **ret_value)


DESCRIPTION
       Wait for the thread to finish executing.  This implicitly calls
       al_set_thread_should_stop(3) first.

       If ret_value is non-NULL, the value returned by the thread function
       will be stored at the location pointed to by ret_value.

SEE ALSO
       al_set_thread_should_stop(3), al_get_thread_should_stop(3),
       al_destroy_thread(3).
