allegro_error - Stores the last Allegro error message.
extern char allegro_error[ALLEGRO_ERROR_SIZE];
Text string used by set_gfx_mode(), install_sound() and other functions to report error messages. If they fail and you want to tell the
user why, this is the place to look for a description of the problem. Example:
void abort_on_error(const char *message)
if (screen != NULL)
set_gfx_mode(GFX_TEXT, 0, 0, 0, 0);
Last Allegro error `%s'
if (some_allegro_function() == ERROR_CODE)
abort_on_error("Error calling some function!");
