64        These routines return the character, of  type  <STRONG>chtype</STRONG>,  at
65        the   current  position  in  the  named  window.   If  any
66        attributes are set for that  position,  their  values  are
67        OR'ed  into  the  value  returned.   Constants  defined in
68        <STRONG>&lt;curses.h&gt;</STRONG> can be used with the <STRONG>&amp;</STRONG> (logical  AND)  operator
69        to extract the character or attributes alone.
