示例1: AddDevices

void InputHandler_MacOSX_HID::AddDevices( int usagePage, int usage, InputDevice &id )
{
	io_iterator_t iter;
	CFDictionaryRef dict = GetMatchingDictionary( usagePage, usage );
	kern_return_t ret = IOServiceAddMatchingNotification( m_NotifyPort, kIOFirstMatchNotification, dict,
						InputHandler_MacOSX_HID::DeviceAdded, this, &iter );
	io_object_t device;

	if( ret != KERN_SUCCESS )
		return;

	m_vIters.push_back( iter );

	// Iterate over the devices and add them
	while( (device = IOIteratorNext(iter)) )
	{
		LOG->Trace( "\tFound device %d", id );
		HIDDevice *dev = MakeDevice( id );
		int num;

		if( !dev )
		{
			LOG->Trace( "\t\tInvalid id, deleting device" );
			IOObjectRelease( device );
			continue;
		}

		if( !dev->Open(device) || (num = dev->AssignIDs(id)) == -1 )
		{
			LOG->Trace( "\tFailed top open or assign id, deleting device" );
			delete dev;
			IOObjectRelease( device );
			continue;
		}
		io_iterator_t i;

		enum_add( id, num );
		m_vDevices.push_back( dev );

		ret = IOServiceAddInterestNotification(
			m_NotifyPort, device, kIOGeneralInterest,
			InputHandler_MacOSX_HID::DeviceChanged,
			this, &i
		);

		if( ret == KERN_SUCCESS )
