Hi all:
I need some advise on getting an IPv6 address to str with variable number of
bytes.
Example:
/* the hex part is */
20 01 db 08 ff ff 00 02 20 86 20 03 de ad be ef
addr_len = 6; /* variable */
/* if I do this: */
addr = tvb_get_ptr(tvb, cur_offset, addr_len);
.... ip6_to_str((const struct e_in6_addr *)addr);
this will result to:
2001:db8:ffff:2:2086:2003:dead:beef
but what i wanted was:
/* the hex part is */
20 01 db 08 ff ff
so it will result to "2001:db8:ffff" (the network portion) coz the "00 02 20 86
20 03 de ad be ef" is for a different purpose.. then I also need to append "::"
to the last part of the str to make it "2001:db8:ffff::"
-----------
I've also tried to use:
bytes_to_str_punct(addr, addr_len, ':')
but this will result to "20:01:db:08:ff:ff"
what is my best approach?
Thanks!
- Ivan
