  70        These  routines  return  a  NULL-terminated array of <STRONG>chtype</STRONG> quantities,
  71        starting at the current cursor position in the named window and  ending
  72        at  the  right  margin of the window.  The four functions with <EM>n</EM> as the
  73        last argument, return a leading substring at  most  <EM>n</EM>  characters  long
  74        (exclusive of the trailing (chtype)0).  Constants defined in <STRONG>&lt;curses.h&gt;</STRONG>
  75        can be used with the <STRONG>&amp;</STRONG> (logical AND) operator to extract the  character
  76        or   the   attribute   alone  from  any  position  in  the  <EM>chstr</EM>  [see
  77        <STRONG><A HREF="curs_inch.3x.html">curs_inch(3x)</A></STRONG>].
  78
  79
  80 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  81        All routines return the integer <STRONG>ERR</STRONG> upon failure and an  integer  value
  82        other than <STRONG>ERR</STRONG> upon successful completion (the number of characters re-
  83        trieved, exclusive of the trailing 0).
  84
  85        X/Open Curses defines no error conditions.  In this implementation:
  86
  87        <STRONG>o</STRONG>   If the <EM>win</EM> parameter is null, an error is returned,
  88
  89        <STRONG>o</STRONG>   If the <EM>chstr</EM> parameter is null, an error is returned,
  90
  91        Functions with a "mv" prefix first  perform  a  cursor  movement  using
  92        <STRONG>wmove</STRONG>, and return an error if the position is outside the window, or if
  93        the window pointer is null.

  97        Note that all routines except <STRONG>winchnstr</STRONG> may be macros.  SVr4  does  not
  98        document whether the result string is zero-terminated; it does not doc-
  99        ument whether a length limit argument includes any trailing 0;  and  it
 100        does not document the meaning of the return value.

 104        These  functions are described in the XSI Curses standard, Issue 4.  It
 105        is no more specific than the SVr4 documentation on the trailing 0.   It
 106        does specify that the successful return of the functions is <STRONG>OK</STRONG>.
