the use sin_zero in sockaddr_in

[prabhu]

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
