allegro_error(3)		 Allegro manual 		allegro_error(3)

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!");
