NAME
allegro_error - Stores the last Allegro error message.SYNOPSIS
#include <allegro.h>extern char allegro_error[ALLEGRO_ERROR_SIZE];
DESCRIPTION
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); allegro_message("%s.\nLast Allegro error `%s'\n", message, allegro_error); exit(-1); } ... if (some_allegro_function() == ERROR_CODE) abort_on_error("Error calling some function!");
