Member Function Documentation

◆ writeHandshake()

bool writeHandshake ( )

Returns true if handshake data was written, false if not.

◆ readHandshake()

bool readHandshake ( )

Returns true if more handshake data needs to be read, false if not.

◆ shutdown()

bool shutdown ( )

If isShutdown() returned false, the shutdown message is written to the output. If isShutdown() returned true, or a previous call of shutdown() returned false, more data is required to read the shutdown reply. True is returned if the shutown was completed.

◆ import()

std::streamsize import ( std::streamsize maxImport = 0 )

Call isShutdown() to find out if a shutdown notify was received and isClosed() if the connection was prematurely closed.

◆ peeksome()

std::streamsize peeksome	(	CharT *	buffer,
		std::streamsize	n
	)

inherited

The number of bytes that can be peeked depends on the current stream buffer get area and maybe less than requested, similar to istream::readsome().
