34  * character set only for now. null-termination not required.
35  * @param str_len length of str
36  * @param pattern pattern string for SQL LIKE
37  * @param pat_len length of pattern
38  * @param escape_char the escape character. '\\' is expected by default.
39  * @param is_ilike true if it is ILIKE, i.e., case-insensitive matching
40  * @return true if str matchs pattern, false otherwise. error condition
41  * not handled for now.
