usetat(3)			Allegro	manual			     usetat(3)

NAME
       usetat -	Replaces a character in	a string. Allegro game programming li-
       brary.

SYNOPSIS
       #include	<allegro.h>

       int usetat(char *s, int index, int c);

DESCRIPTION
       Replaces	the character at the specified index in	the string with	 value
       `c',  handling  any adjustments for variable width data (ie. if `c' en-
       codes to	a different width than the previous value at  that  location).
       If  `index' is negative,	it counts backward from	the end	of the string.
       Example:

	  usetat(text_string, 2, letter_a);

RETURN VALUE
       Returns the number of bytes by which the	trailing part  of  the	string
       was  moved.  This  is of	interest only with text	encoding formats where
       characters have a variable length, like UTF-8.
