Hi!

As explain in another thread, on the unix port, the address returned by recvfrom() socket method is in the raw form (16 bytes).
A friend explained me it matches the C struct:

    struct sockaddr {
        sa_family_t sa_family;
        char        sa_data[14];
    }

In practice, this is an union, depending on the familly. For IPv4:

    struct sockaddr_in {
        sa_family_t    sin_family; /* address family: AF_INET */
        in_port_t      sin_port;   /* port in network byte order */
        struct in_addr sin_addr;   /* internet address */
    };

In my case, I get the raw data \x02\x00\x0e\x57\xc0\xa8\x00\x92\x00\x00\x00\x00\x00\x00\x00\x00 which matches ('192.168.0.146', 3671).

The question is: why the raw data isn't converted in a more useful tuple (ip, port) under the unix port, while it is on the rp2 port, for example, and on CPython? Is it a bug? A feature?

Thanks,

Frédéric
