void al_join_thread(ALLEGRO_THREAD *thread, void **ret_value)
Introduced in 5.0.0

Wait for the thread to finish executing. This implicitly calls al_set_thread_should_stop 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, al_get_thread_should_stop, al_destroy_thread.

Examples: ex_threads, ex_threads2
