empty_string(3)			Allegro	manual		       empty_string(3)

NAME
       empty_string  - Universal string	NULL terminator. Allegro game program-
       ming 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  run-
       ning in ASCII, Unicode, or UTF-8	mode.

Allegro				 version 4.4.3		       empty_string(3)
