NAME

       register_uformat - Installs handler functions for a new text encoding format. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       void  register_uformat(int type, int (*u_getc)(const char *s), int (*u_getx)(char **s), int (*u_setc)(char *s, int c), int (*u_width)(const
       char *s), int (*u_cwidth)(int c), int (*u_isok)(int c));

DESCRIPTION

       Installs a set of custom handler functions for a new text encoding format. The `type' is the ID code for your new format, which should be a
       4-character  string  as	produced  by  the AL_ID() macro, and which can later be passed to functions like set_uformat() and uconvert(). The
       function parameters are handlers that implement the character access for your new type: see below for details of these.
