<H2><a name="h2-DESCRIPTION">DESCRIPTION</a></H2><PRE>
       These functions extract the complex character  and  rendi-
       tion  from  the  current position in the named window into
       the <STRONG>cchar_t</STRONG> object referenced by wcval.


</PRE>
<H2><a name="h2-RETURN-VALUE">RETURN VALUE</a></H2><PRE>
       No errors are defined in the XSI  Curses  standard.   This
       implementation  checks  for  null pointers, returns ERR in
       that case.  Also, the <EM>mv</EM> routines check for  error  moving
       the  cursor,  returning  ERR in that case.  Otherwise they
       return OK

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


</PRE>
<H2><a name="h2-NOTES">NOTES</a></H2><PRE>
       Note that all of these routines may be macros.

       These functions are described in the XSI Curses  standard,
       Issue 4.
