SYNOPSIS

9              #include <allegro5/allegro.h>
10
11              size_t al_ustr_set_chr(ALLEGRO_USTR *us, int start_pos, int32_t c)
12

DESCRIPTION

14       Replace the code point beginning at byte offset pos with c.  pos cannot
15       be less than 0.  If pos is past the end of us1 then the  space  between
16       the end of the string and pos will be padded with NUL (`\0') bytes.  If
17       pos is not the start of a valid code point, that is an  error  and  the
18       string will be unmodified.
19
20       On success, returns the number of bytes written, i.e. the offset to the
21       following code point.  On error, returns 0.
