Detailed Description

template<typename Stream, typename Service = old::stream_service>
class asio::ssl::old::stream< Stream, Service >

Provides stream-oriented functionality using SSL.

The stream class template provides asynchronous and blocking stream-oriented functionality using SSL.

Thread Safety: Distinct objects: Safe.
Shared objects: Unsafe.

Example: To use the SSL stream template with an ip::tcp::socket, you would write:
asio::io_service io_service;
asio::ssl::context context(io_service, asio::ssl::context::sslv23);
asio::ssl::stream<asio::ip::tcp::socket> sock(io_service, context);

Concepts:: AsyncReadStream, AsyncWriteStream, Stream, SyncRead_Stream, SyncWriteStream.

	)

inlineexplicit

Construct a stream.

This constructor creates a stream and initialises the underlying stream object.

Parameters

arg	The argument to be passed to initialise the underlying stream.
context	The SSL context to be used for the stream.

template<typename HandshakeHandler >

void asio::ssl::old::stream< Stream, Service >::async_handshake	(	handshake_type	type,
		HandshakeHandler	handler
	)

inline

Start an asynchronous SSL handshake.

This function is used to asynchronously perform an SSL handshake on the stream. This function call always returns immediately.

Parameters

type	The type of handshaking to be performed, i.e. as a client or as a server.
handler	The handler to be called when the handshake operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be: void handler( const asio::error_code& error // Result of operation. );

Definition at line 209 of file stream.hpp.

template<typename Stream , typename Service = old::stream_service>

template<typename MutableBufferSequence , typename ReadHandler >

void asio::ssl::old::stream< Stream, Service >::async_read_some	(	const MutableBufferSequence &	buffers,
		ReadHandler	handler
	)

inline

Start an asynchronous read.

This function is used to asynchronously read one or more bytes of data from the stream. The function call always returns immediately.

Parameters

buffers	The buffers into which the data will be read. Although the buffers object may be copied as necessary, ownership of the underlying buffers is retained by the caller, which must guarantee that they remain valid until the handler is called.
handler	The handler to be called when the read operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be: void handler( const asio::error_code& error, // Result of operation. std::size_t bytes_transferred // Number of bytes read. );

Note: The async_read_some operation may not read all of the requested number of bytes. Consider using the asio::async_read function if you need to ensure that the requested amount of data is read before the asynchronous operation completes.

Definition at line 407 of file stream.hpp.

template<typename Stream , typename Service = old::stream_service>

template<typename ShutdownHandler >

void asio::ssl::old::stream< Stream, Service >::async_shutdown ( ShutdownHandler handler )

inline

Asynchronously shut down SSL on the stream.

This function is used to asynchronously shut down SSL on the stream. This function call always returns immediately.

Parameters

handler

The handler to be called when the handshake operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be:

 void handler(
  const asio::error_code& error // Result of operation.
); 

Definition at line 253 of file stream.hpp.

template<typename Stream , typename Service = old::stream_service>

template<typename ConstBufferSequence , typename WriteHandler >

void asio::ssl::old::stream< Stream, Service >::async_write_some	(	const ConstBufferSequence &	buffers,
		WriteHandler	handler
	)

inline

Start an asynchronous write.

This function is used to asynchronously write one or more bytes of data to the stream. The function call always returns immediately.

Parameters

buffers	The data to be written to the stream. Although the buffers object may be copied as necessary, ownership of the underlying buffers is retained by the caller, which must guarantee that they remain valid until the handler is called.
handler	The handler to be called when the write operation completes. Copies will be made of the handler as required. The equivalent function signature of the handler must be: void handler( const asio::error_code& error, // Result of operation. std::size_t bytes_transferred // Number of bytes written. );

Note: The async_write_some operation may not transmit all of the data to the peer. Consider using the asio::async_write function if you need to ensure that all data is written before the blocking operation completes.

Definition at line 329 of file stream.hpp.
