  63        These functions extract the complex character  and  rendi-
  64        tion  from  the  current position in the named window into
  65        the <STRONG>cchar_t</STRONG> object referenced by wcval.

  69        No errors are defined in the XSI  Curses  standard.   This
  70        implementation  checks  for  null pointers, returns ERR in
  71        that case.  Also, the <EM>mv</EM> routines check for  error  moving
  72        the  cursor,  returning  ERR in that case.  Otherwise they
  73        return OK
  74
  75        Functions with a "mv" prefix first perform a cursor  move-
  76        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  77        outside the window, or if the window pointer is null.
