sockaddr_in Struct Reference

Socket address structure for IPV4 addresses. Used to specify socket address information to connect to. Can be cast to sockaddr structure.

#include <socket.h>

Data Fields
in_addr	sin_addr
uint16	sin_family
uint16	sin_port
uint8	sin_zero [8]

in_addr sockaddr_in::sin_addr

IP Address of the socket. The IP address is of type in_addr structure. Can be set to "0" to accept any IP address for server operation.

uint16 sockaddr_in::sin_family

Specifies the address family(AF). Members of AF_INET address family are IPv4 addresses. Hence,the only supported value for this is AF_INET.

uint16 sockaddr_in::sin_port

Port number of the socket. Network sockets are identified by a pair of IP addresses and port number. It must be set in the Network Byte Order format , _htons (e.g. _htons(80)). Can NOT have zero value.

uint8 sockaddr_in::sin_zero[8]

Padding to make structure the same size as sockaddr.
