# socket.h(3)

Network addresses and sockets related classes.

## NAME

socket.h - Network addresses and sockets related classes.

## SYNOPSIS

`#include <cc++/address.h>`\

### Classes

class **ost::Socket**\
 The **Socket** is used as the base for all Internet protocol services under Common C++.  class **ost::DCCPSocket**\
 DCCP sockets are used for stream based connected sessions between two sockets.  class **ost::UDPSocket**\
 UDP sockets implement the TCP SOCK\_DGRAM UDP protocol.  class **ost::UDPBroadcast**\
 Representing a UDP socket used for subnet broadcasts, this class provides an alternate binding and setPeer() capability for UDP sockets.  class **ost::UDPTransmit**\
 Representing half of a two-way UDP connection, the UDP transmitter can broadcast data to another selected peer host or to an entire subnet.  class **ost::UDPReceive**\
 Representing half of a two-way UDP connection, the UDP receiver can receive data from another peer host or subnet.  class **ost::UDPDuplex**\
 UDP duplex connections impliment a bi-directional point-to-point UDP session between two peer hosts.  class **ost::TCPSocket**\
 TCP sockets are used for stream based connected sessions between two sockets.  class **ost::TCPV6Socket**\
 TCPV6 sockets are used for stream based connected sessions between two ipv6 sockets.  class **ost::TCPStream**\
 TCP streams are used to represent TCP client connections to a server by TCP protocol servers for accepting client connections.  class **ost::TCPSession**\
 The TCP session is used to primarily to represent a client connection that can be managed on a separate thread.  class **ost::SimpleTCPStream**\
 Simple TCP Stream, to be used with Common C++ Library.
