basic_socket::close (1 of 2 overloads)

Close the socket.

void close();

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.



Thrown on failure. Note that, even if the function indicates an error, the underlying descriptor is closed.


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