Function Documentation

comm_read_base()

void comm_read_base	(	const Comm::ConnectionPointer &	conn,
		char *	buf,
		int	size,
		AsyncCall::Pointer &	callback
	)

Queue a read. If a buffer is given the callback is scheduled when the read completes, on error, or on file descriptor close.

If no buffer (NULL) is given the callback is scheduled when the socket FD is ready for a read(2)/recv(2).

comm_read_cancel()

void comm_read_cancel	(	int	fd,
		IOCB *	callback,
		void *	data
	)

Cancel a pending read. Assert that we have the right parameters, and that there are no pending read events!

XXX: We do not assert that there are no pending read events and with async calls it becomes even more difficult. The whole interface should be reworked to do callback->cancel() instead of searching for places where the callback may be stored and updating the state of those places.

AHC Don't call the comm handlers?
