Yes the above case is clear: if someone supplies 0/0, s/he will probably not want any specialised protocols in the return list. This didn't appear in Remi's list. I have completed the list and put the cases in the table below; `defaults' is interpreted in the way above. +--------------+---------------+---------------+---------------+ | ai_socktype | ai_protocol | Return type | Return Proto | +--------------+---------------+---------------+---------------+ | SOCK_DCCP | IPPROTO_DCCP | SOCK_DCCP | IPPROTO_DCCP | | SOCK_DCCP | 0 | SOCK_DCCP | IPPROTO_DCCP | | 0 | IPPROTO_DCCP | SOCK_DCCP | IPPROTO_DCCP | | 0 | 0 | (defaults) | (defaults) | +--------------+---------------+---------------+---------------+ If at all possible, for UDP-Lite it is similar. Since UDP-Lite is actually just a form of UDP, this seems much less urgent than DCCP - one might argue that UDP-Lite falls under SOCK_DGRAM/UDP. +-------------+-----------------+-------------+-----------------+ | ai_socktype | ai_protocol | Return type | Return Proto | +-------------+-----------------+-------------+-----------------+ | SOCK_DGRAM | IPPROTO_UDPLITE | SOCK_DGRAM | IPPROTO_UDPLITE | | SOCK_DGRAM | 0 | SOCK_DGRAM | IPPROTO_UDP | | 0 | IPPROTO_UDPLITE | SOCK_DGRAM | IPPROTO_UDPLITE | | 0 | 0 | (defaults) | (defaults) | +-------------+-----------------+-------------+-----------------+ ... but it would still be good to have. -- To unsubscribe from this list: send the line "unsubscribe dccp" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
