+/*
+ * 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)
