  66        These functions extract the complex character  and  rendi-
  67        tion  from  the  current position in the named window into

  73        No errors are defined in the XSI  Curses  standard.   This
  74        implementation  checks  for  null pointers, returns ERR in
  75        that case.  Also, the <EM>mv</EM> routines check for  error  moving
  76        the  cursor,  returning  ERR in that case.  Otherwise they
  77        return OK
  78
  79        Functions with a "mv" prefix first perform a cursor  move-
  80        ment  using  <STRONG>wmove</STRONG>, and return an error if the position is
  81        outside the window, or if the window pointer is null.
