basic_socket::close (2 of 2 overloads)

Close the socket.

void close(
    asio::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 asio::error::operation_aborted error.

Parameters

ec: Set to indicate what error occurred, if any. Note that, even if the function indicates an error, the underlying descriptor is closed.

Example

asio::ip::tcp::socket socket(my_context);
...
asio::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.
