/*

 *  NOTE:

 *	  int  mblen (char *s, size_t n);

 *

 *	  where	     n: a maximum number of bytes

 *

 *	  return - the number of bytes

 *

 *  CAUTION:

 *

 *	 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 set a 'NULL', it doens't mean a NULL pointer.

 *

 *	 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_mblen(), set

 *	   ret_flg=0 always. It's a special case, and the test

 *	   function takes care of it.

 *

 *	       s_flg=0		 ret_flg=0

 *	       |		 |

 *	     { 0, 0 },	 { 0, 0, 0,  x }

 *		  |		     |

 *		  not used	     ret_val: 0/+1
