    curs_addchstr(3x)                Library calls               curs_addchstr(3x)

## NAME

           addchstr,  addchnstr,  waddchstr,  waddchnstr, mvaddchstr, mvaddchnstr,
           mvwaddchstr, mvwaddchnstr - add a curses character string to a 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
           returns 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.
