 *  TEST SUITE FOR MB/WC FUNCTIONS IN C LIBRARY

 */

/*  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.

 *

 *			  w_flg

 *			  |	s: (a null string; can't be (char *)NULL)

 *			  |	|

 *	       input.	{ 1, 0, (char)NULL, MB_LEN_MAX	},

 *			     |

 *			     s_flg=0: makes _s_ a null pointer.

 *

 *	       expect	{ 0,0,0,x,     0x0000	  },

 *			      | |

 *			      | ret_val: 0/+1

 *			      ret_flg=0

 *

 *

 *    Test data for State dependent encodings:

 *

 *	  mbtowc( NULL, NULL, 0 );	 ... first  data

 *	  mbtowc( &wc,	s1,  n1 );	 ... second data

 *	  mbtowc( &wc,	s2,  n2 );	 ... third  data
