boost::corosio::tcp

Encapsulate the TCP protocol for socket creation.

Synopsis

Declared in <boost/corosio/tcp.hpp>

class tcp;

Description

This class identifies the TCP protocol and its address family (IPv4 or IPv6). It is used to parameterize socket and acceptor open() calls with a self‐documenting type.

The family(), type(), and protocol() members return the three integers passed to the operating system's socket() call. Their values are platform‐defined constants taken from the system socket headers. For an inline variant that includes those headers, use native_tcp.

Example

tcp_acceptor acc( ioc );
acc.open( tcp::v6() );  // IPv6 socket
acc.set_option( socket_option::reuse_address( true ) );
acc.bind( endpoint( ipv6_address::any(), 8080 ) );
acc.listen();
