# al\_join\_thread(3alleg5)

Allegro 5 API

## 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(3alleg5) 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(3alleg5), al\_get\_thread\_should\_stop(3alleg5), al\_destroy\_thread(3alleg5).
