RFID_STATUS WINAPI RFID_FujitsuReadBlockLock	(	RFID_HANDLE32	readerHandle,
		UINT8 *	pTagID,
		UINT32	tagIDLength,
		FUJITSU_READ_BLOCKLOCK_ACCESS_PARAMS *	lpReadBlockLockParams,
		LPACCESS_FILTER	lpAccessFilter,
		LPANTENNA_INFO	lpAntennaInfo,
		TAG_DATA *	lpTagData,
		LPVOID	rsvd
	)

This function reads the status of Block-Lock flags of a particular BlockGroup on one or more Fujitsu tags in the FOV.

Parameters:

`[in]`	readerHandle	Handle to the RFID device.
`[in]`	pTagID	Pointer to the byte array containing Tag ID
`[in]`	tagIDLength	Length of the byte array containing Tag ID
`[in]`	lpReadBlockLockAcessParams	Pointer to FUJITSU_READ_BLOCKLOCK_ACCESS_PARAMS structure containing the BlockGroup's offset.
`[in]`	lpAccessFilter	Pointer to Access filter structure specifying the tag-filter criteria for the current Access operation
`[in]`	lpAntennaInfo	Pointer to ANTENNA_INFO structure specifying the Antenna IDs on which the access operation is to be performed
`[out]`	lpTagData	Pointer to Tag_DATA structure which indicates among others the "blockLock-status" of the given BlockGroup.
`[in]`	rsvd	Reserved for future use

Returns:

If the function succeeds the return value is RFID_API_SUCCESS. If the function fails the return value is one of the following:

RFID_API_INVALID_HANDLE Handle provided is invalid
RFID_API_PARAM_ERROR Parameter is invalid.

RFID_ACCESS_FUJITSU_READ_BLOCKLOCK_FAILED Failed to change BlockLock flags on the specified tag(s)

Remarks:: The TAG_DATA structure contains a Pointer to ACCESS_OPERATION_RESULT which contains a union of results for certain Access Operations, one among them being FujitsuReadBlockLockResult. This result is a 16-bit pattern or "blockLock-status" which specifies the states of the BlockLock flags for the given BlockGroup.
