Constructor & Destructor Documentation

BazisLib::DDK::StorageFilter::StorageFilter	(	LPCWSTR	pwszBaseDeviceName,
		bool	bDeleteThisAfterRemoveRequest = false,
		LPCWSTR	pwszFilterDeviceName = NULL,
		DEVICE_TYPE	FilterDeviceType = FILE_DEVICE_UNKNOWN,
		ULONG	DeviceCharacteristics = FILE_DEVICE_SECURE_OPEN,
		bool	bExclusive = FALSE,
		ULONG	AdditionalDeviceFlags = DO_POWER_PAGABLE
	)

Initializes a storage filter class instance

Parameters:

bDeleteThisAfterRemoveRequest

Specifies whether the device object (class instance) should be deleted automatically after handling IRP_MN_REMOVE_DEVICE.
