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

  77        The  following  bit-masks  may  be  AND-ed with characters
  78        returned by <STRONG>winch</STRONG>.
  79
  80        <STRONG>A_CHARTEXT</STRONG>     Bit-mask to extract character
  81        <STRONG>A_ATTRIBUTES</STRONG>   Bit-mask to extract attributes

  87        Functions with a "mv" prefix first perform a cursor  move-
  88        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  89        outside the window, or if the window pointer is null.
