Inherited from basic_socket.
Release ownership of the underlying native socket.
native_handle_type release();
This function causes all outstanding asynchronous connect, send and receive
operations to finish immediately, and the handlers for cancelled operations
will be passed the asio::error::operation_aborted
error. Ownership of the native socket is then transferred to the caller.
Thrown on failure.
This function is unsupported on Windows versions prior to Windows 8.1,
and will fail with asio::error::operation_not_supported
on these platforms.
