/*
|
|
* 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
|
|
* (expected val) */
