## 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.
