    curs_addchstr(3x)                                            curs_addchstr(3x)

## NAME

           addchstr, addchnstr, waddchstr, waddchnstr, mvaddchstr, mvaddchnstr,
           mvwaddchstr, mvwaddchnstr - add a string of characters (and attributes)
           to a curses window

## SYNOPSIS

           #include <curses.h>

           int addchstr(const chtype *chstr);
           int addchnstr(const chtype *chstr, int n);
           int waddchstr(WINDOW *win, const chtype *chstr);
           int waddchnstr(WINDOW *win, const chtype *chstr, int n);

           int mvaddchstr(int y, int x, const chtype *chstr);
           int mvaddchnstr(int y, int x, const chtype *chstr, int n);
           int mvwaddchstr(WINDOW *win, int y, int x, const chtype *chstr);
           int mvwaddchnstr(WINDOW *win, int y, int x, const chtype *chstr, int n);

## DESCRIPTION

           These  functions copy the (null-terminated) chstr array into the window
           image structure starting at the  current  cursor  position.   The  four
           functions  with  n as the last argument copy at most n elements, but no
           more than will fit on the line.   If  n=-1  then  the  whole  array  is
           copied, to the maximum number of characters that will fit on the line.

           The  window  cursor  is not advanced.  These functions work faster than
           waddnstr.  On the other hand:

           o   they do not perform checking (such as for the  newline,  backspace,
               or carriage return characters),

           o   they do not advance the current cursor position,

           o   they do not expand other control characters to ^-escapes, and

           o   they  truncate  the  string  if it crosses the right margin, rather
               than wrapping it around to the new line.

## RETURN VALUE

           All functions return the integer ERR upon failure and OK on success.

           X/Open does not define any error conditions.  This  implementation  re-
           turns an error if the window pointer is null.

           Functions  with  a  "mv"  prefix  first perform a cursor movement using
           wmove, and return an error if the position is outside the window, or if
           the window pointer is null.

## NOTES

           All functions except waddchnstr may be macros.

## PORTABILITY

           These entry points are described in the XSI Curses standard, Issue 4.
