       addchstr, addchnstr, waddchstr, waddchnstr, mvaddchstr, mvaddchnstr, mvwaddchstr,
       mvwaddchnstr - add a string of characters (and attributes) to a curses 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 work faster than waddnstr.  On the
       other hand:

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

       ·   they do not advance the current cursor position,

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

       ·   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 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.


       All functions except waddchnstr may be macros.


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