NAME

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

SYNOPSIS

10       #include <allegro.h>
11
12
13       int usetat(char *s, int index, int c);
14

DESCRIPTION

16       Replaces the character at the specified index in the string with  value
17       `c',  handling  any  adjustments  for  variable  width data (ie. if `c'
18       encodes to a different width than the previous value at that location).
19       If  `index' is negative, it counts backward from the end of the string.
20       Example:
21
22          usetat(text_string, 2, letter_a);
23

RETURN VALUE

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