  67 <H2>DESCRIPTION</H2><PRE>
  68        These routines return  a  string  of  characters  in  <EM>str</EM>,
  69        extracted  starting  at the current cursor position in the
  70        named window.  Attributes are stripped  from  the  charac-
  71        ters.   The  four  functions  with  <EM>n</EM> as the last argument
  72        return a leading  substring  at  most  <EM>n</EM>  characters  long
  73        (exclusive of the trailing NUL).
  74
  75
  76 </PRE>
  77 <H2>RETURN VALUE</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
  82 </PRE>
  83 <H2>NOTES</H2><PRE>
  84        Note that all routines except <STRONG>winnstr</STRONG> may be macros.
  85
  86
  87 </PRE>
  88 <H2>PORTABILITY</H2><PRE>
  89        The XSI Curses error  conditions  <STRONG>EILSEQ</STRONG>  and  <STRONG>EILOVERFLOW</STRONG>
  90        associated  with  extended-level  conformance  are not yet
  91        detected (this implementation does not  yet  support  XPG4
  92        multibyte  characters).   SVr4 does not document whether a
  93        length limit includes or excludes the trailing NUL.
  94
  95        The ncurses library extends the XSI description by  allow-
  96        ing  a  negative value for <EM>n</EM>.  In this case, the functions
  97        return the string ending at the right margin.
