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

       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 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.
