/*
 *  FUNCTION:
 *
 *	  int  wctomb (char *s, wchar_t wc);
 *
 *	       return: the number of bytes
 *
 *  NOTE:
 *
 *	 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_wctomb(), set
 *	   ret_flg=0 always. It's a special case, and the test
 *	   function takes care of it.
 *
 *	      Input	  Expect
 *
 *		s_flg=0		  ret_flg=0
 *		|		  |
 *	      { 0, 0 },	  { 0, 0, 0,  x,  "" }
 *		   |		      |
 *		   not used	      ret_val: 0/+1
 * (expected val)
