IOCTL_MOUNTDEV_LINK_CREATED	0x4dc010	inc\ddk\mountdev.h	Support for this IOCTL by the mount manager clients is optional. The mount manager uses this IOCTL to alert the client driver that a persistent name has been assigned to its volume. The input for this IOCTL is the persistent name assigned.
IOCTL_MOUNTDEV_LINK_DELETED	0x4dc014	inc\ddk\mountdev.h	Support for this IOCTL by the mount manager clients is optional. It alerts the mount manager client that a persistent name associated with it has been deleted. The input for this IOCTL is the persistent name that was deleted.

IOCTL_MOUNTDEV_QUERY_SUGGESTED_LINK_NAME	0x4d000c	inc\ddk\mountdev.h	Support for this IOCTL by the mount manager clients is optional. Some mount manager clients are able to keep track of their drive letters across reboots of the system without the help of the mount manager. Such clients can send a suggested drive letter name to the mount manager in response to this IOCTL. The mount manager uses the suggested name if the mount manager's database does not already contain a persistent drive letter name for the client's volume. Otherwise, it ignores the suggestion and uses the drive letter name in its persistent name database.

IOCTL_MOUNTMGR_CHECK_UNPROCESSED_VOLUMES	0x6d4028	inc\ddk\mountmgr.h	When a volume arrives in the system, it registers for the MOUNTDEV_MOUNTED_DEVICE_GUID interface class and the mount manager receives a Plug and Play notification (seeMount Manager I/O Control Codesfor a discussion of this process). When the mount manager receives this notification, it queries the client driver that manages the volume for the volume's unique ID. In some cases, however, particularly with clusters, the client notifies the mount manager of the arrival of its volume, but then does not respond when queried for the volume's unique ID. The mount manager keeps these volumes in adead mounted devicelist. Clients can use the IOCTL_MOUNTMGR_CHECK_UNPROCESSED_VOLUMES IOCTL to request that the mount manager rescan its dead mounted device list and make another attempt to query the clients on the list for the unique IDs of their respective volumes.
IOCTL_MOUNTMGR_CREATE_POINT	0x6dc000	inc\ddk\mountmgr.h	The mount manager clients can use this IOCTL to request that the mount manager create a persistent symbolic link name for the indicated volume.

IOCTL_MOUNTMGR_KEEP_LINKS_WHEN_OFFLINE	0x6dc024	inc\ddk\mountmgr.h	This IOCTL directs the mount manager to keep a symbolic link active after the Plug and Play manager has given notification that its corresponding volume has gone offline.

IOCTL_MOUNTMGR_QUERY_AUTO_MOUNT	0x6d003c	inc\ddk\mountmgr.h	This IOCTL returns triples that consist of a persistent symbolic link name for the volume (that is, a mount point), a unique ID for the volume, and a nonpersistent device name (such as "\Device\HarddiskVolume1") for the volume.

If a client does not register a device interface of type MOUNTDEV_MOUNTED_DEVICE_GUID, the mount manager is not alerted of its arrival. However, the client can alert the mount manager of its volume's arrival directly by means of this IOCTL.
IOCTL_MOUNTMGR_VOLUME_MOUNT_POINT_CREATED	0x6dc018	inc\ddk\mountmgr.h
IOCTL_MOUNTMGR_VOLUME_MOUNT_POINT_DELETED	0x6dc01c	inc\ddk\mountmgr.h	The mount manager clients use this IOCTL to alert the mount manager that a volume mount point has been deleted so that the mount manager can replicate the database entry for the given mount point.

The behavior of the storage device when a Persistent Reserve In command is received is described in theSCSI Primary Commands - 2 (SPC-2)specification. The IOCTL interface requires the caller to have read access to the physical device for Persistent Reserve In commands. User-mode applications, services, and kernel-mode drivers can use this IOCTL to control persistent reservations. If called from a driver, this IOCTL must be called from a thread running at IRQL < DISPATCH_LEVEL. This IOCTL is defined with FILE_READ_ACCESS, requiring a device handle to have read permissions to issue the Persistent Reserve In command.
IOCTL_STORAGE_PERSISTENT_RESERVE_OUT	0x2dd01c	inc\api\ntddstor.h	The generic storage class driver (classpnp.sys) exposes an I/O control (IOCTL) interface for issuing Persistent Reserve Out commands. The behavior of the storage device when a Persistent Reserve Out command is received is described in theSCSI Primary Commands - 2 (SPC-2)specification. The IOCTL interface requires the caller to have read/write access to the physical device for Persistent Reserve Out commands. User-mode applications, services, and kernel-mode drivers can use this IOCTL to control persistent reservations. If called from a driver, this IOCTL must be called from a thread running at IRQL < DISPATCH_LEVEL. This IOCTL is defined with FILE_READ_ACCESS and FILE_WRITE_ACCESS, requiring a device handle to have both read and write permissions to issue the Persistent Reserve Out command.

IOCTL_STORAGE_RESET_DEVICE	0x2d5004	inc\api\ntddstor.h	If possible, resets a non-SCSI storage device without affecting other devices on the bus. Device reset for SCSI devices is not supported.

After the display device switch, the video signal can be sent to one or both display devices. When the video port driver receives a notification to switch display devices, it sends this IOCTL to the miniport driver. Normally, this IOCTL is sent afterIOCTL_VIDEO_VALIDATE_CHILD_STATE_CONFIGURATIONindicates that the miniport driver is ready to make the switch.

IOCTL_VIDEO_SET_COLOR_REGISTERS	0x23041c	inc\api\ntddvdeo.h	Sets the adapter's color registers to the specified RGB values. If the adapter has a color look up table (CLUT), sometimes called a palette, the miniport driver is required to support this modal request.
IOCTL_VIDEO_SET_CURRENT_MODE	0x23040c	inc\api\ntddvdeo.h	Sets the adapter to the specified operating mode. Miniport drivers are required to support this nonmodal request because it resets the current mode. The miniport driver must also consider the two high order flags which are used to additionally control the mode set operation. SeeVIDEO_MODEfor further information.
IOCTL_VIDEO_SET_CURSOR_ATTR	0x230428	inc\api\ntddvdeo.h	Sets the cursor size, position, and visibility. Miniport drivers for VGA-compatible adapters are required to support this request, which is modal. Support is optional for other miniport drivers.

When a miniport driver fails this request, the corresponding display driver must manage the pointer.
IOCTL_VIDEO_SET_POINTER_POSITION	0x230448	inc\api\ntddvdeo.h	Sets the pointer position. Support for this modal request is optional. A supporting miniport driver should have already processed an enable-pointer request before processing this request.
IOCTL_VIDEO_SET_POWER_MANAGEMENT	0x23046c	inc\api\ntddvdeo.h	This IOCTL isobsoletein Windows 2000 and later, and is no longer supported. A Plug and Play video miniport driver should implement theHwVidSetPowerStatefunction, which provides similar functionality.

IOCTL_VIDEO_VALIDATE_CHILD_STATE_CONFIGURATION	0x230484	inc\api\ntddvdeo.h	Queries the miniport driver to determine whether it is ready for a display device switch. This switch is a state change in which the video signal going to one display device is sent to another, possibly different type of display device. After the display device switch, the video signal can be sent to one or both display devices. When the video port driver receives a request to switch display devices (by, for example, a hotkey being pressed), it sends this IOCTL to the video miniport driver. The value returned by the miniport driver indicates whether the video port driver should proceed with the display device switch.
IOCTL_VOLSNAP_FLUSH_AND_HOLD_WRITES	0x53c000	inc\ddk\ntifs.h	The IOCTL_VOLSNAP_FLUSH_AND_HOLD_WRITES control code is sent to force a flush of a file system before a volume shadow copy occurs. This IOCTL is issued as an IRP_MJ_DEVICE_CONTROL request that is sent only to the volume device object of a local file system and to file system filter drivers that may have attached to that volume. This IOCTL is most commonly sent by the Volume Shadow Copy Service, but it can also be issued by other user-mode applications or processes. It is also possible under special circumstances for this IOCTL to be sent by the Volume Shadow Copy Driver (volsnap.sys) during a hibernation request or before a crash dump. This IOCTL is sent to file system filter drivers, file system drivers, and other device drivers (storage filter drivers and storage drivers, for example) located below the file systems.
