       addwstr, addnwstr, waddwstr, waddnwstr, mvaddwstr,
       mvaddnwstr, mvwaddwstr, mvwaddnwstr - add a string of wide
       characters to a curses window and advance cursor


       #include <curses.h>

       int addwstr(const wchar_t *wstr);
       int addnwstr(const wchar_t *wstr, int n);
       int waddwstr(WINDOW *win, const wchar_t *wstr);
       int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);
       int mvaddwstr(int y, int x, const wchar_t *wstr);
       int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
       int mvwaddwstr(WINDOW *win, int y, int x, const wchar_t *wstr);

       These  functions  write the characters of the (null-termi-
       nated) wchar_t character string wstr on the given  window.
       It  is  similar to constructing a cchar_t for each wchar_t
       in the string, then calling  wadd_wch  for  the  resulting

       The  mv  functions  perform  cursor  movement once, before
       writing any characters.  Thereafter,  the  cursor  is  ad-
       vanced as a side-effect of writing to the window.

       The  four  functions  with n as the last argument write at
       most n wchar_t characters, or until a terminating null  is
       reached.   If  n  is  -1,  then  the entire string will be


       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

       o   if the window pointer is null or

       o   if the string pointer is null or

       o   if the corresponding calls to wadd_wch return  an  er-

       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.


       All of these functions except waddnwstr may be macros.


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