NAME
al_get_system_config - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro.h>
ALLEGRO_CONFIG *al_get_system_config(void)
DESCRIPTION
Returns the current system configuration structure, or NULL if there is no active system driver. The
returned configuration should not be destroyed with al_destroy_config(3alleg5). This is mainly used for
configuring Allegro and its addons.
Allegro will try to populate this configuration by loading a configuration file from a few different
locations, in this order:
• Unix only: /etc/allegro5rc
• Unix only: $HOME/allegro5rc
• allegro5.cfg next to the executable
If multiple copies are found, then they are merged using al_merge_config_into(3alleg5).
The contents of this file are documented inside a prototypical allegro5.cfg that you can find in the root
directory of the source distributions of Allegro. Note that Allegro will not look into that file unless
you make a copy of it and place it next to your executable!
