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(3NCURSES) with the resulting cchar_t.

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

       •   control characters are processed as in wadd_wch(3NCURSES).

       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(3NCURSES) 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

       •   if the window pointer is NULL,

       •   if the string pointer is NULL, or

       •   if an internal wadd_wch(3NCURSES) 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.
