NAME         top

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

SYNOPSIS         top

       #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);
       int mvwaddnwstr(WINDOW *win, int y, int x, const wchar_t *wstr, int n);

DESCRIPTION         top

       These functions write the characters of the (null-terminated)
       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 cchar_t.

       The mv functions perform cursor movement once, before writing any
       characters.  Thereafter, the cursor is advanced 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 added.

RETURN VALUE         top

       All functions return the integer ERR upon failure and OK on

       X/Open does not define any error conditions.  This implementation
       returns an error

       •   if the window pointer is null or

       •   if the string pointer is null or

       •   if the corresponding calls to wadd_wch return an error.

       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.

NOTES         top

       All of these functions except waddnwstr may be macros.

PORTABILITY         top

       These functions are described in the XSI Curses standard, Issue
