struct sockaddr_in
{
short sin_family; // AF_INET
u_short sin_port; // 16 bit Port Number in network byte order
struct in_addr sin_addr; // 32 bit netid/hostid in network byte order
char sin_zero[8]; // unused
};
The sin_family member should be set to AF_INET (=2).
The sin_addr member's in_addr structure is simply a long IP address in big endian byte order.
The htons function can be used to convert port numbers to network byte order.
