◆ DiskStore_GetData()

void DiskStore_GetData	(	DiskStore *	store,
		uint64_t	slotID,
		Packet *	npkt,
		struct rte_mbuf *	dataBuf,
		BdevStoredPacket *	sp
	)

Retrieve a Data packet.

Parameters

slotID	disk slot number.
npkt	an Interest packet. DiskStore takes ownership until callback.
dataBuf	a uniquely owned, unsegmented, direct mbuf for Data packet. DiskStore takes ownership until callback.
sp	same `BdevStoredPacket` used during PutData, will be copied.

This function asynchronously reads from a specified slot of the underlying disk, and parses the content as a Data packet. Upon success, it assigns interest->diskSlot and interest->diskData . Upon failure, it assigns interest->diskSlot and clears interest->diskData . It then calls store->getDataCb with the npkt .

This function may be invoked on any thread, including non-SPDK thread.

◆ DiskStore_PutData()

void DiskStore_PutData	(	DiskStore *	store,
		uint64_t	slotID,
		Packet *	npkt,
		BdevStoredPacket *	sp
	)

Store a Data packet.

Parameters

slotID	disk slot number; slot 0 cannot be used.
npkt	a Data packet. DiskStore takes ownership.
sp	output of a successful `DiskStore_PrepareData` .

This function may be invoked on any thread, including non-SPDK thread.
