Detailed Description

template<typename HOOKS, typename BR_MAN = Br_manager_no_buffers>
class L4::Ipc_svr::Timeout_queue_hooks< HOOKS, BR_MAN >

Loop hooks mixin for integrating a timeout queue into the server loop.

Template Parameters

HOOKS	has to inherit from Timeout_queue_hooks<> and provide the functions now() that has to return the current time.
BR_MAN	This used as a base class for and provides the API for selecting the buffer register (BR) that is used to store the timeout value. This is usually L4Re::Util::Br_manager or L4::Ipc_svr::Br_manager_no_buffers.

Member Function Documentation

template<typename HOOKS , typename BR_MAN = Br_manager_no_buffers>

int L4::Ipc_svr::Timeout_queue_hooks< HOOKS, BR_MAN >::add_timeout	(	Timeout *	timeout,
		l4_kernel_clock_t	time
	)

inlineoverridevirtual

Add a timeout to the queue for time time.

Parameters

timeout	The timeout object to add into the queue (must not be in any queue currently).
time	The time when the timeout shall expire.

Note: The timeout is automatically dequeued before the Timeout::expired() function is called

template<typename HOOKS , typename BR_MAN = Br_manager_no_buffers>

int L4::Ipc_svr::Timeout_queue_hooks< HOOKS, BR_MAN >::remove_timeout ( Timeout * timeout )

inlineoverridevirtual

Remove timeout from the queue.

Parameters

timeout The timeout object to be removed from the queue.

Note: This function may be safely called even if the timeout is not currently enqueued.; in Timeout::expired() the timeout is already dequeued!
