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  for-
     mat.  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.

Allegro 			  version 4.4.3 		 empty_string(3)
