empty_string(3) Allegro manual empty_string(3)NAMEempty_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.
