Asynchronously shut down SSL on the stream.
template< typename ShutdownToken = DEFAULT> DEDUCED async_shutdown( ShutdownToken && token = DEFAULT);
This function is used to asynchronously shut down SSL on the stream. It is an initiating function for an asynchronous operation, and always returns immediately.
The completion
token that will be used to produce a completion handler, which
will be called when the shutdown completes. Potential completion
tokens include use_future
, use_awaitable
, yield_context
, or a function
object with the correct completion signature. The function signature
of the completion handler must be:
void handler( const asio::error_code& error // Result of operation. );
Regardless of whether the asynchronous operation completes immediately
or not, the completion handler will not be invoked from within this
function. On immediate completion, invocation of the handler will
be performed in a manner equivalent to using post
.
void(asio::error_code)
This asynchronous operation supports cancellation for the following cancellation_type
values:
cancellation_type::terminal
cancellation_type::partial
if they are also supported by the Stream
type's async_read_some
and async_write_some
operations.
