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!");
