void inj_init_queue ( inj_queue * q )

Initializes an injection queue.

Making it empty.

Parameters:

q	The injection queue to be initialized.

void inj_ins_mult_queue	(	inj_queue *	q,
		phit *	i,
		long	copies
	)

Inserts some clones of a phit in an injection queue.

Requires enough space. Otherwise, panics.

Parameters:

q	An injection queue.
i	The phit to be inserted.
copies	Number of copies of i.

void inj_ins_queue	(	inj_queue *	q,
		phit *	i
	)

Inserts a phit in an injection queue.

Requires a buffer with room for the phit. Otherwise, panics

Parameters:

q	An injection queue.
i	The phit to insert.

long inj_queue_len ( inj_queue * q )

Calculates the length of an injection queue.

Parameters:

q	An injection queue.

Returns:: The number of phits in the injection queue.

long inj_queue_space ( inj_queue * q )

Calculates the free space in an injection queue.

Parameters:

q	An injection queue.

Returns:: the number of free phits in the injection queue.

void inj_rem_queue	(	inj_queue *	q,
		phit *	i
	)

Take the first phit in an injection queue.

Removes the head phit from the injection queue & returns it. Requires a non-empty queue. Otherwise, panics.

Parameters:

q	An injection queue.
i	The removed phit is returned here.
