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

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

  79        Reading a line that overflows the  array  pointed  to  by  <EM>wchstr</EM>  with
  80        <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wchstr</STRONG> causes undefined re-
  81        sults.  Therefore, the use of <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>,  <STRONG>mvwin_wchnstr</STRONG>,
  82        or <STRONG>win_wchnstr</STRONG> is recommended.

  86        Upon successful completion, these functions return <STRONG>OK</STRONG>.  Otherwise, they
  87        return <STRONG>ERR</STRONG>.
  88
  89        Functions with a "mv" prefix first  perform  a  cursor  movement  using
  90        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
  91        the window pointer is null.

  95        The XSI Curses defines no error conditions.  This implementation checks
  96        for null pointers, returning <STRONG>ERR</STRONG> in that case.
