  71 <H2>DESCRIPTION</H2><PRE>
  72        These functions return an array of complex  characters  in
  73        <EM>wchstr</EM>,  starting  at  the  current cursor position in the
  74        named window.  Attributes (rendition) are stored with  the
  75        characters.
  76
  77        The  <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG> and <STRONG>win_wchn-</STRONG>
  78        <STRONG>str</STRONG> fill the array with at most <EM>n</EM> <STRONG>cchar_t</STRONG> elements.
  79
  80
  81 </PRE>
  82 <H2>NOTES</H2><PRE>
  83        Note that all routines except <STRONG>win_wchnstr</STRONG> may be macros.
  84
  85        Reading a line that overflows the array pointed to by <EM>wch-</EM>
  86        <EM>str</EM>  with <STRONG>in_wchstr</STRONG>, <STRONG>mvin_wchstr</STRONG>, <STRONG>mvwin_wchstr</STRONG> or <STRONG>win_wch-</STRONG>
  87        <STRONG>str</STRONG>  causes  undefined  results.  Therefore,  the  use  of
  88        <STRONG>in_wchnstr</STRONG>, <STRONG>mvin_wchnstr</STRONG>, <STRONG>mvwin_wchnstr</STRONG>, or <STRONG>win_wchnstr</STRONG> is
  89        recommended.
  90
  91
  92 </PRE>
  93 <H2>RETURN VALUES</H2><PRE>
  94        Upon successful completion,  these  functions  return  <STRONG>OK</STRONG>.
  95        Otherwise, they return <STRONG>ERR</STRONG>.
  96
  97        Functions  with a "mv" prefix first perform a cursor move-
  98        ment using <STRONG>wmove</STRONG>, and return an error if the  position  is
  99        outside the window, or if the window pointer is null.
 100
 101
 102 </PRE>
 103 <H2>PORTABILITY</H2><PRE>
 104        The  XSI  Curses defines no error conditions.  This imple-
 105        mentation checks for null pointers, returning ERR in  that
 106        case.
