get comment of a member id - structure type ID member_offset - member offset. The offset can be any offset in the member. For example, is a member is 4 bytes long and starts at offset 2, then 2, 3, 4, 5 denote the same structure member. repeatable - 1: get repeatable comment 0: get regular comment returns: 0 if bad structure type ID is passed or no such member in the structure otherwise returns comment of the specified member.
string get_member_cmt(long id, long member_offset, long repeatable);
