NAME

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

SYNOPSIS

       #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

       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

       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 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

       All of these functions except waddnwstr may be macros.

PORTABILITY

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