Detect a TLS/SSL handshake asynchronously on a stream.
Defined in header <boost/beast/core/detect_ssl.hpp>
template< class AsyncReadStream, class DynamicBuffer, class CompletionToken = net::default_completion_token_t<beast::executor_type<AsyncReadStream>>> DEDUCED async_detect_ssl( AsyncReadStream& stream, DynamicBuffer& buffer, CompletionToken&& token = net::default_completion_token_t< beast::executor_type< AsyncReadStream > >{});
This function reads asynchronously from a stream to determine if a client handshake message is being received.
This call always returns immediately. The asynchronous operation will continue until one of the following conditions is true:
The algorithm, known as a composed asynchronous operation,
is implemented in terms of calls to the next layer's async_read_some
function. The program must ensure that no other calls to async_read_some
are performed until this operation completes.
Bytes read from the stream will be stored in the passed dynamic buffer, which may be used to perform the TLS handshake if the detector returns true, or be otherwise consumed by the caller based on the expected protocol.

The dynamic buffer to use. This type must meet the requirements of DynamicBuffer. |

The completion token used to determine the method used to provide the result of the asynchronous operation. If this is a completion handler, the implementation takes ownership of the handler by performing a decay-copy, and the equivalent function signature of the handler must be: void handler( error_code const & error, // Set to the error, if any bool result // The result of the detector );
If the handler has an associated immediate executor, an immediate
completion will be dispatched to it. Otherwise, the handler will
not be invoked from within this function. Invocation of the handler
will be performed in a manner equivalent to using |
