RFID_STATUS WINAPI RFID_FujitsuAreaWriteLockWOPassword	(	RFID_HANDLE32	readerHandle,
		UINT8 *	pTagID,
		UINT32	tagIDLength,
		FUJITSU_AREA_WRITELOCK_WOPASSWORD_ACCESS_PARAMS *	lpAreaWriteLockWOPasswordParams,
		ACCESS_FILTER *	lpAccessFilter,
		ANTENNA_INFO *	lpAntennaInfo,
		LPVOID	rsvd
	)

This function sets the WriteLock flags of upto sixteen Areas in the specified AreaGroup of one 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]`	lpAreaWriteLockWOPasswordAcessParams	Pointer to FUJITSU_AREA_WRITELOCK_WOPASSWORD_ACCESS_PARAMS structure containing the AreaGroup's offset and Payload Action which specifes for which of the 16 Areas,the WriteLock flag needs to be set.
`[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
`[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_AREA_WRITELOCK_WOPASSWORD_FAILED Failed to set WriteLock flags on the specified tag(s)

Remarks:: It can set the WriteLock flags of upto 16 areas in the given AreaGroup,because of which the words enclosed in the corresponding areas become write-locked.Unlike the AreaWriteLock operation, it can only Write-lock an area,but cannot unlock and as the name indicates,it doesn't require the ** AreaGroup's password.
