  69        These routines return  a  string  of  characters  in  <EM>str</EM>,
  70        extracted  starting  at the current cursor position in the
  71        named window.  Attributes are stripped  from  the  charac-
  72        ters.   The  four  functions  with  <EM>n</EM> as the last argument
  73        return a leading  substring  at  most  <EM>n</EM>  characters  long
  74        (exclusive of the trailing NUL).
  75
  76
  77 </PRE><H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
  78        All  of the functions return <STRONG>ERR</STRONG> upon failure, or the num-
  79        ber of characters actually read into the string.
  80
  81        X/Open defines no error conditions.  In  this  implementa-
  82        tion, if the window parameter is null or the str parameter
  83        is null, a zero is returned.
  84
  85        Functions with a "mv" prefix first perform a cursor  move-
  86        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  87        outside the window, or if the window pointer is null.

  95        SVr4 does not document whether a length limit includes  or
  96        excludes the trailing NUL.
  97
  98        The  ncurses library extends the XSI description by allow-
  99        ing a negative value for <EM>n</EM>.  In this case,  the  functions
 100        return the string ending at the right margin.
