       add_wchstr, add_wchnstr, wadd_wchstr, wadd_wchnstr, mvadd_wchstr,
       mvadd_wchnstr, mvwadd_wchstr, mvwadd_wchnstr - add an array of complex
       characters (and attributes) to a curses window

       #include <curses.h>

       int add_wchstr(const cchar_t *wchstr);
       int add_wchnstr(const cchar_t *wchstr, int n);
       int wadd_wchstr(WINDOW * win, const cchar_t *wchstr);
       int wadd_wchnstr(WINDOW * win, const cchar_t *wchstr, int n);
       int mvadd_wchstr(int y, int x, const cchar_t *wchstr);
       int mvadd_wchnstr(int y, int x, const cchar_t *wchstr, int n);
       int mvwadd_wchstr(WINDOW *win, int y, int x, const cchar_t *wchstr);
       int mvwadd_wchnstr(WINDOW *win, int y, int x, const cchar_t *wchstr, int n);

       These  functions copy the (null-terminated) array of complex characters
       wchstr into the window image structure starting at the  current	cursor
       position.   The four functions with n as the last argument copy at most
       n elements, but no more than will fit on the line.  If  n=-1  then  the
       whole  array  is	 copied, to the maximum number of characters that will
       fit on the line.

       The window cursor is not advanced.  These functions  work  faster  than
       waddnstr.  On the other hand:

       ·   they	 do  not perform checking (such as for the newline, backspace,
	   or carriage return characters),

       ·   they do not advance the current cursor position,

       ·   they do not expand other control characters to ^-escapes, and

       ·   they truncate the string if it crosses  the	right  margin,	rather
	   than wrapping it around to the new line.

       These  functions	 end  successfully  on encountering a null cchar_t, or
       when they have filled the current line.	If a complex character	cannot
       completely  fit	at  the end of the current line, the remaining columns
       are filled with the background character and rendition.

       All functions return the integer ERR upon failure and OK on success.

       X/Open does not define any error conditions.  This  implementation  re‐
       turns an error if the window pointer is null.

       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.

       All functions except wadd_wchnstr may be macros.

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

       curs_addwstr(3X), curses(3X).

       Comparable  functions in the narrow-character (ncurses) library are de‐
       scribed in curs_addchstr(3X).
