the use sin_zero in sockaddr_in

[prabhu <prabhum@xxxxxxxxxxxxx>]

Hi all,

Could anyone please explain the use sin_zero in sockaddr_in?

struct sockaddr_in{
        short    sin_family;    /* AF_INET */
        u_short    sin_port;        /* 16-bit port number */
                    /* network byte ordered */
        struct in_addr sin_addr;    /* 32-bit netid/hostid */
                    /* network byte ordered */
        char    sin_zero[8];    /* unused */
}

Thanks,
Prabhu
