Linux Network programming-----socket Address API

(1) Universal socket address

The socket network programming interface that represents the socket address is the struct sockaddr, which is defined as follows:

#include <bits/socket.h>

struct SOCKADDR

{

sa_family_t sa_family;

Char sa_data[14];

}

(2) New generic socket address structure

#include <bits/socket.h>

struct Sockaddr_storage

{

sa_family_t sa_family;

unsigned long int _ss_align;

Char _ss_padding[128-sizeof (__ss_align)];

}

(3) Dedicated socket address
