    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 in-
           to the window image structure starting at the current cur-
           sor position.  The four functions with n as the last argu-
           ment 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  ^-es-
               capes, and

           o   they  truncate the string if it crosses the right mar-
               gin, 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 imple-
           mentation returns an error if the window pointer is null.

           Functions with a "mv" prefix first perform a cursor  move-
           ment  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.
