Function Documentation

CsArc_Add()

void CsArc_Add	(	CsArc *	arc,
		CsEntry *	entry
	)

Add or refresh an entry.

Precondition

PCC entry is populated.

If entry is already in ARC, entry->kind reflects its old value.

CsArc_Init()

void CsArc_Init	(	CsArc *	arc,
		uint32_t	c,
		uint32_t	capB2
	)

Initialize ARC.

Parameters

c	nominal capacity.
capB2	extended capacity of B2 list, used in CsDisk integration.

CsArc_Remove()

void CsArc_Remove	(	CsArc *	arc,
		CsEntry *	entry
	)

Remove an entry.
