... ;
struct {
ULONG DeviceType;
} MountVolume;
... ;
} FLT_PARAMETERS, *PFLT_PARAMETERS;
Members

DeviceType: Device type of the file system's volume device object for the newly mounted volume. One of the following:
- FILE_DEVICE_CD_ROM_FILE_SYSTEM
- FILE_DEVICE_DISK_FILE_SYSTEM
- FILE_DEVICE_NETWORK_FILE_SYSTEM
Remarks
The FLT_PARAMETERS structure for IRP_MJ_VOLUME_MOUNT operations contains the parameters for a volume-mount operation represented by a callback data (FLT_CALLBACK_DATA) structure. It is contained in an FLT_IO_PARAMETER_BLOCK structure.
