Referenced by DBus::BusDispatcher::enter(), and read().

signal()

void Pipe::signal

(

)

Simply write one single byte into the pipe. This is a shortcut if there's really no data to transport, but to activate the handler.

write()

void Pipe::write	(	const void *	buffer,
		unsigned int	nbytes
	)

Write some data into the communication pipe.

Parameters

buffer	The raw data to write.
nbytes	The number of bytes to write from the buffer.
