empty_string - Universal string NULL terminator. Allegro game

NAME

       empty_string   -   Universal   string  NULL  terminator.  Allegro  game
       programming library.

SYNOPSIS

       #include <allegro.h>

       extern char empty_string[];

DESCRIPTION

       You can't just rely on "" to be a valid empty string  in  any  encoding
       format.  This  global buffer contains a number of consecutive zeros, so
       it will be a valid empty  string  no  matter  whether  the  program  is
       running in ASCII, Unicode, or UTF-8 mode.
