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


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


       #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);


       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 are 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.


       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

       o   if the win parameter is null or

       o   if the wchstr parameter 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.


       All functions except waddchnstr may be macros.


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