RFID_STATUS WINAPI RFID_RegisterEventNotificationCallback	(	RFID_HANDLE32	readerHandle,
		RFID_EVENT_TYPE *	pEvents,
		UINT32	numEvents,
		RfidEventCallbackFunction	pFnRfidEventCallbackFunction,
		LPVOID	rsvd1,
		LPVOID	rsvd2
	)

This function is used to enable notification of a group of events. Callback mechanism of event handling and win32-event based event handlings are mutually exclusive. Hence application shall stick to one mechanism and not attempt a combination of the two event handling mechanisms.

Parameters:

`[in]`	readerHandle	Handle to the RFID device.
`[in]`	pEvents	array of RFID_EVENT_TYPE that needs to be registered.
`[in]`	numEvents	Number of events being provided in pEvents.
`[in]`	pFnRfidEventCallbackFunction	Function pointer which receives Event notifications.

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 Invalid handle is provided
RFID_API_PARAM_ERROR Invalid parameter given

Remarks:: The application shall create array of RFID_EVENT_TYPE with the events of interest and a callback function RfidEventCallbackFunction which shall receive the callback upon occurance of a registered event.

Remarks:

Example: See

RFID_HANDLE32 readerHandle;
RFID_STATUS rfidStatus = RFID_API_SUCCESS;
VERSION_INFO versionInfo;

if(RFID_API_SUCCESS == RFID_Connect(&readerHandle, TEXT("157.235.207.88"), 0, 0, NULL))
{
RFID_EVENT_TYPE rfidEvents[12] = 
{
GPI_EVENT, TAG_READ_EVENT, BUFFER_FULL_EVENT, BUFFER_FULL_WARNING_EVENT, 
ANTENNA_EVENT, DISCONNECTION_EVENT, 
INVENTORY_START_EVENT, INVENTORY_STOP_EVENT, ACCESS_START_EVENT, ACCESS_STOP_EVENT, READER_EXCEPTION_EVENT
};

rfidStatus = RFID_RegisterEventNotificationCallback(readerHandle, rfidEvents,  12, (RfidEventCallbackFunction) rfidEventCallback, NULL, NULL);

// perform required operations

rfidStatus = RFID_Disconnect(readerHandle);
