A buffered_handshake token is a completion
token for completion signature void(error_code, size_t)
.
A free function as a buffered_handshake token:
void buffered_handshake_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... }
A buffered_handshake token function object:
struct buffered_handshake_handler { ... void operator()( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... };
A lambda as a buffered_handshake token:
ssl_stream.async_handshake(..., [](const asio::error_code& ec, std::size_t bytes_transferred) { ... });
A non-static class member function adapted to a buffered_handshake token
using std::bind()
:
void my_class::buffered_handshake_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... ssl_stream.async_handshake(..., std::bind(&my_class::buffered_handshake_handler, this, std::placeholders::_1, std::placeholders::_2));
A non-static class member function adapted to a buffered_handshake token
using boost::bind()
:
void my_class::buffered_handshake_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... ssl_stream.async_handshake(..., boost::bind(&my_class::buffered_handshake_handler, this, asio::placeholders::error, asio::placeholders::bytes_transferred));
Using use_future as a buffered handshake token:
std::future<std::size_t> f = ssl_stream.async_handshake(..., asio::use_future); ... try { std::size_t n = f.get(); ... } catch (const system_error& e) { ... }
Using use_awaitable as a buffered handshake token:
asio::awaitable<void> my_coroutine() { try { ... std::size_t n = co_await ssl_stream.async_handshake( ..., asio::use_awaitable); ... } catch (const system_error& e) { ... } }
