al_install_system(3)al_install_system(3)NAMEal_install_system - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro.h>
bool al_install_system(int version, int (*atexit_ptr)(void (*)(void)))
DESCRIPTION
Initialize the Allegro system. No other Allegro functions can be
called before this (with one or two exceptions).
The version field should always be set to ALLEGRO_VERSION_INT.
If atexit_ptr is non-NULL, and if hasn't been done already, al_unin‐
stall_system(3) will be registered as an atexit function.
Returns true if Allegro was successfully initialized by this function
call (or already was initialized previously), false if Allegro cannot
be used.
