<H2>DESCRIPTION</H2><PRE>
       These functions return an array of complex  characters  in
       <EM>wchstr</EM>,  starting  at  the  current cursor position in the
       named window.  Attributes (rendition) are stored with  the
       characters.

       The  <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
       <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.


</PRE>
<H2>NOTES</H2><PRE>
       Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.

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


</PRE>
<H2>RETURN VALUE</H2><PRE>
       Upon successful completion,  these  functions  return  <STRONG>OK</STRONG>.
       Otherwise, they return <STRONG>ERR</STRONG>.

       Functions  with a "mv" prefix first perform a cursor move-
       ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
       outside the window, or if the window pointer is null.


</PRE>
<H2>PORTABILITY</H2><PRE>
       The  XSI  Curses defines no error conditions.  This imple-
       mentation checks for null pointers, returning ERR in  that
       case.
