  70 <H2>DESCRIPTION</H2><PRE>
  71        These  routines  return  a string of <STRONG>wchar_t</STRONG> characters in
  72        <EM>wstr</EM>, extracted starting at the current cursor position in
  73        the  named window.  Attributes are stripped from the char-
  74        acters.  The four functions with <EM>n</EM> as  the  last  argument
  75        return a leading substring at most <EM>n</EM> bytes long (exclusive
  76        of the trailing NUL).  Transfer stops at the  end  of  the
  77        current  line,  or  when  <EM>n</EM>  bytes have been stored at the
  78        location referenced by <EM>wstr</EM>.
  79
  80        If the size <EM>n</EM> is not large  enough  to  store  a  complete
  81        character, an error is generated.
  82
  83
  84 </PRE>
  85 <H2>NOTES</H2><PRE>
  86        Note that all routines except <STRONG>winnwstr</STRONG> may be macros.
  87
  88
  89 </PRE>
  90 <H2>RETURN VALUES</H2><PRE>
  91        All routines return <STRONG>ERR</STRONG> upon failure. Upon successful com-
  92        pletion, the *<STRONG>inwstr</STRONG> routines return <STRONG>OK</STRONG>, and the  *<STRONG>innwstr</STRONG>
  93        routines  return  the  number  of characters read into the
  94        string.
  95
  96        Functions with a "mv" prefix first perform a cursor  move-
  97        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  98        outside the window, or if the window pointer is null.
