basic_stream_socket::async_connect Home Libraries People FAQ More basic_stream_socket::async_connect Inherited from basic_socket. Start an asynchronous connect. template<
typename ConnectHandler>
void async_connect(
const endpoint_type & peer_endpoint,
ConnectHandler handler);
This function is used to asynchronously connect a socket to the specified remote endpoint. The function call always returns immediately. The socket is automatically opened if it is not already open. If the connect fails, and the socket was automatically opened, the socket is not returned to the closed state. Parameters peer_endpoint The remote endpoint to which the socket will be connected. Copies will be made of the endpoint object as required. handler The handler to be called when the connection operation completes. Copies will be made of the handler as required. The function signature of the handler must be: void handler(
const boost::system::error_code& error // Result of operation
);
Regardless of whether the asynchronous operation completes immediately or not, the handler will not be invoked from within this function. Invocation of the handler will be performed in a manner equivalent to using boost::asio::io_service::post(). Example void connect_handler(const boost::system::error_code& error)
{
if (!error)
{
// Connect succeeded.
}
}
...
boost::asio::ip::tcp::socket socket(io_service);
boost::asio::ip::tcp::endpoint endpoint(
boost::asio::ip::address::from_string("1.2.3.4"), 12345);
socket.async_connect(endpoint, connect_handler);
