empty_string(3)                 Allegro manual                 empty_string(3)



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.
