al_init(3)                                                          al_init(3)

NAME
       al_init - Allegro 5 API

SYNOPSIS

              #include <allegro5/allegro.h>

              #define al_init()    (al_install_system(ALLEGRO_VERSION_INT, atexit))


DESCRIPTION
       Like al_install_system(3), but automatically passes in the version and
       uses the atexit function visible in the current binary.

              Note: It is typically wrong to call al_init anywhere except the
              final game binary.  In particular, do not call it inside a
              shared library unless you know what you're doing.  In those
              cases, it is better to call al_install_system either with a NULL
              atexit_ptr, or with a pointer to atexit provided by the user of
              this shared library.
