basic_datagram_socket::close (2 of 2 overloads)

Inherited from basic_socket.

Close the socket.

boost::system::error_code close(
    boost::system::error_code & ec);

This function is used to close the socket. Any asynchronous send, receive or connect operations will be cancelled immediately, and will complete with the boost::asio::error::operation_aborted error.

Parameters

ec

Set to indicate what error occurred, if any.

Example
boost::asio::ip::tcp::socket socket(io_service);
...
boost::system::error_code ec;
socket.close(ec);
if (ec)
{
  // An error occurred.
}
Remarks

For portable behaviour with respect to graceful closure of a connected socket, call shutdown() before closing the socket.
