void do_event	(	event_q *	q,
		event *	i
	)

Uses the first event in the queue.

Takes an event an increases its packet count. When it reaches the length of the event, this is erased from the queue.

Parameters:

q	A pointer to a queue.
i	A pointer to the event to do.

bool_t event_empty ( event_q * q )

Is a queue empty?.

Parameters:

q	A pointer to the queue.

Returns:: TRUE if the queue is empty FALSE in other case.

event head_event ( event_q * q )

Looks at the first event in a queue.

Parameters:

q	A pointer to the queue.

Returns:: The first event in the queue (without using nor modifying it).

void init_event ( event_q * q )

Initializes an event queue.

Parameters:

q	a pointer to the queue to be initialized.

void init_occur ( event_l * l )

Initializes all ocurred events lists.

There is only one list in each router.

Parameters:

l	A pointer to the list to be initialized.

void ins_event	(	event_q *	q,
		event	i
	)

Adds an event to a queue.

Parameters:

q	a pointer to a queue.
i	the event to be added to q.

void ins_occur	(	event_l *	l,
		event	i
	)

Inserts an event's occurrence in an event list.

If the event is in the list, then its count is increased. Otherwise a new event is created in the occurred event list.

Parameters:

l	A pointer to a list.
i	The event to be added.

bool_t occurred	(	event_l *	l,
		event	i
	)

Has an event completely occurred?.

If it has totally occurred, this is, the event is in the list and its count is equal to its length, then it is deleted from the list.

Parameters:

l	a pointer to a list.
i	the event we are seeking for.

Returns:: TRUE if the event has been occurred, elseway FALSE

void rem_head_event ( event_q * q )

Deletes the first event in a queue.

Parameters:

q	A pointer to the queue.
