    curs_addwstr(3x)                 Library calls                curs_addwstr(3x)

## NAME

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

## SYNOPSIS

           #include <curses.h>

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

           int addnwstr(const wchar_t *wstr, int n);
           int mvaddnwstr(int y, int x, const wchar_t *wstr, int n);
           int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);
           int waddnwstr(WINDOW *win, const wchar_t *wstr, int n);

## DESCRIPTION

           waddwstr  writes  the  characters  of  the (wide-null-terminated) wide-
           character string wstr to the window win.  Its  process  is  similar  to
           constructing   a  cchar_t  for  each  wchar_t  in  wstr,  then  calling
           wadd_wch(3x) with the resulting cchar_t.

           o   Spacing and non-spacing characters in the string are processed  one
               at a time, and

           o   control characters are processed as in wadd_wch(3x).

           waddnwstr writes at most n wide characters, or until a terminating wide
           null character occurs in wstr.  If n is -1, waddnwstr writes the entire
           wide string.

           ncurses(3x) describes the variants of these functions.

## RETURN VALUE

           These functions return OK on success and ERR on failure.

           X/Open  Curses  does not specify any error conditions.  ncurses returns
           an error

           o   if the window pointer is NULL,

           o   if the string pointer is NULL, or

           o   if an internal wadd_wch(3x) call returns an error.

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

## NOTES

           All of these functions except waddnwstr may be implemented as macros.

## PORTABILITY

           X/Open Curses, Issue 4 describes these functions.

## SEE ALSO

           curs_addstr(3x)  describes  comparable functions of the ncurses library
           in its non-wide-character configuration.
