/*  NOTE:
 *
 *	 int  mbtowc (wchar_t *wp, char *s, size_t n);
 *
 *	 where	     n: a maximum number of bytes
 *		return: the number of bytes
 *
 *
 *	  o When you feed a null pointer for a string (s) to the function,
 *	    set s_flg=0 instead of putting just a 'NULL' there.
 *	    Even if you put a 'NULL', it means a null string as well as "".
 *
 *	  o When s is a null pointer, the function checks state dependency.
 *
 *		state-dependent encoding      - return	NON-zero
 *		state-independent encoding    - return	0
 *
 *	    If state-dependent encoding is expected, set
 *
 *		s_flg = 0,  ret_flg = 0,  ret_val = +1
 *
 *	    If state-independent encoding is expected, set
 *
 *		s_flg = 0,  ret_flg = 0,  ret_val = 0
 *
 *
 *	    When you set ret_flg=1, the test program simply compares
 *	    an actual return value with an expected value. You can
 *	    check state-independent case (return value is 0) in that
 *	    way, but you can not check state-dependent case. So when
 *	    you check state- dependency in this test function:
 *	    tst_mbtowc(), set ret_flg=0 always. It's a special case
 *	    and the test function takes care of it.
