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