  69        These functions return an array of complex  characters  in
  70        <EM>wchstr</EM>,  starting  at  the  current cursor position in the
  71        named window.  Attributes (rendition) are stored with  the
  72        characters.
  73
  74        The  <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
  75        <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.

  79        Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.

  81        Reading a line that overflows the array pointed to by <EM>wch-</EM>
  82        <EM>str</EM>  with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
  83        <STRONG>str</STRONG>  causes  undefined  results.  Therefore,  the  use  of
  84        <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
  85        recommended.

  88 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  89        Upon successful completion,  these  functions  return  <STRONG>OK</STRONG>.
  90        Otherwise, they return <STRONG>ERR</STRONG>.
  91
  92        Functions  with a "mv" prefix first perform a cursor move-
  93        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
  94        outside the window, or if the window pointer is null.

  98        The  XSI  Curses defines no error conditions.  This imple-
  99        mentation checks for null pointers, returning ERR in  that
 100        case.
