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

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

SYNOPSIS
       #include <ncursesw/curses.h>

       int addchstr(const chtype * chstr);
       int waddchstr(WINDOW * win, const chtype * chstr);
       int mvaddchstr(int y, int x, const chtype * chstr);
       int mvwaddchstr(WINDOW * win, int y, int x,
             const chtype * chstr);

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

DESCRIPTION
       waddchstr copies the string of curses characters chstr  to  the  window
       win.   A  null curses character terminates the string.  waddchnstr does
       the same, but copies at most n characters, or as many as possible if  n
       is -1.  ncurses(3X) describes the variants of these functions.

       Because  these  functions  do  not call waddch(3X) internally, they are
       faster than waddstr(3X) and waddnstr(3X).  On the other hand, they

       •   do not treat the backspace, carriage return, or line  feed  charac‐
           ters specially;

       •   do not represent unprintable characters with unctrl(3X);

       •   do  not  update  the  cursor  position to follow the last character
           written;

       •   truncate the string at the window's right margin, rather than wrap‐
           ping it to the next line and potentially scrolling.

RETURN VALUE
       These functions return OK on success and ERR on failure.

       In ncurses, these functions fail if

       •   the curses screen has not been initialized,

       •   chstr is a null pointer, or

       •   (for functions taking a WINDOW pointer  argument)  win  is  a  null
           pointer.

       Functions  prefixed with “mv” first perform cursor movement and fail if
       the position (y, x) is outside the window boundaries.

PORTABILITY
       X/Open Curses Issue 4 describes these functions.  It specifies no error
       conditions for them.

       SVr4  describes  a  successful  return  value only as “an integer value
       other than ERR”.

HISTORY
       SVr3.1 (1987) introduced these functions.

SEE ALSO

       brary in its wide-character configuration (ncursesw).
