Detailed Description

The DtMsgSocket provides a wrapper around the DtInetSocket class to operate on messages rather than just raw data.

Constructor & Destructor Documentation

DtMsgSocket::DtMsgSocket	(	DtBoost::shared_ptr< DtMsgHeaderReader >	hdrReader,
		size_t	recvBuffSize
	)

Constructor.

Requires a header reader to extract information from message headers.

DtMsgSocket::DtMsgSocket	(	std::auto_ptr< DtInetSocket >	socket,
		DtBoost::shared_ptr< DtMsgHeaderReader >	hdrReader,
