  71 <H2>DESCRIPTION</H2><PRE>
  72        These routines return  a  string  of  characters  in  <EM>str</EM>,
  73        extracted  starting  at the current cursor position in the
  74        named window.  Attributes are stripped  from  the  charac-
  75        ters.   The  four  functions  with  <EM>n</EM> as the last argument
  76        return a leading  substring  at  most  <EM>n</EM>  characters  long
  77        (exclusive of the trailing NUL).
  78
  79
  80 </PRE>
  81 <H2>RETURN VALUE</H2><PRE>
  82        All  of the functions return <STRONG>ERR</STRONG> upon failure, or the num-
  83        ber of characters actually read into the string.
  84
  85        X/Open defines no error conditions.  In  this  implementa-
  86        tion, if the window parameter is null or the str parameter
  87        is null, a zero is returned.
  88
  89        Functions with a "mv" prefix first perform a cursor  move-
  90        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  91        outside the window, or if the window pointer is null.
  92
  93
  94 </PRE>
  95 <H2>NOTES</H2><PRE>
  96        Note that all routines except <STRONG>winnstr</STRONG> may be macros.
  97
  98
  99 </PRE>
 100 <H2>PORTABILITY</H2><PRE>
 101        SVr4 does not document whether a length limit includes  or
 102        excludes the trailing NUL.
 103
 104        The  ncurses library extends the XSI description by allow-
 105        ing a negative value for <EM>n</EM>.  In this case,  the  functions
 106        return the string ending at the right margin.
