SOCKADDR_IN

  • Article

In the Internet address family, this structure is used by Windows Sockets to specify a local or remote endpoint address to which to connect a socket. This is the form of the SOCKADDR structure specific to the Internet address family and can be cast to SOCKADDR.

struct sockaddr_in{
 short sin_family;
 unsigned short sin_port;
 IN_ADDR sin_addr;
 char sin_zero[8];};

Members

  • sin_family
    Address family; must be AF_INET.
  • sin_port
    Internet Protocol (IP) port.
  • sin_addr
    IP address in network byte order.
  • sin_zero
    Padding to make structure the same size as SOCKADDR.

Remarks

The IP address component of this structure is of type IN_ADDR. The IN_ADDR structure is defined in Windows Sockets header file Winsock.h as follows:

typedef struct in_addr {
 union {
 struct{
 unsigned char s_b1,
 s_b2,
 s_b3,
 s_b4;
 } S_un_b;
 struct {
 unsigned short s_w1,
 s_w2;
 } S_un_w;
 unsigned long S_addr;
 } S_un;
} IN_ADDR;

Requirements

Runs on Versions Defined in Include Link to
Windows CE OS 1.0 and later Winsock.h
