NAME

       usetat - Replaces a character in a string. Allegro game programming library.

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'
       encodes 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.
