mountmgr.h contains the following programming interfaces:

IOCTLs

IOCTL_MOUNTDEV_QUERY_DEVICE_NAME Support for this IOCTL by the mount manager clients is mandatory.
IOCTL_MOUNTMGR_AUTO_DL_ASSIGNMENTS This IOCTL informs the mount manager that it should assign drive letters to volumes automatically as they are introduced in the system.
IOCTL_MOUNTMGR_CHANGE_NOTIFY Clients send this IOCTL to the mount manager to be informed whenever there is a change in the mount manager's persistent symbolic link name database.
IOCTL_MOUNTMGR_CHECK_UNPROCESSED_VOLUMES 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 (see Mount Manager I/O Control Codes for a discussion of this process).
IOCTL_MOUNTMGR_CREATE_POINT 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_DELETE_POINTS This IOCTL is identical in input and output to IOCTL_MOUNTMGR_QUERY_POINTS. The difference is that IOCTL_MOUNTMGR_DELETE_POINTS has the side effect of deleting the symbolic links and the mount manager database entries for the triples returned.
IOCTL_MOUNTMGR_DELETE_POINTS_DBONLY This IOCTL is identical in input and output to IOCTL_MOUNTMGR_QUERY_POINTS.
IOCTL_MOUNTMGR_KEEP_LINKS_WHEN_OFFLINE 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_NEXT_DRIVE_LETTER This IOCTL checks to see if the given volume has a drive letter.
IOCTL_MOUNTMGR_QUERY_POINTS 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.
IOCTL_MOUNTMGR_VOLUME_ARRIVAL_NOTIFICATION This IOCTL allows a client to simulate a Plug and Play device interface arrival notification with the given volume name.
IOCTL_MOUNTMGR_VOLUME_MOUNT_POINT_CREATED This IOCTL alerts the mount manager that a volume mount point has been created, so that the mount manager can replicate the database entry for the given mount point.
IOCTL_MOUNTMGR_VOLUME_MOUNT_POINT_DELETED 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.

Structures

MOUNTDEV_NAME The MOUNTDEV_NAME structure holds the name of a device.
MOUNTMGR_CHANGE_NOTIFY_INFO The MOUNTMGR_CHANGE_NOTIFY_INFO structure is used by the mount manager to send epic numbers to its clients and vice versa.
MOUNTMGR_CREATE_POINT_INPUT The MOUNTMGR_CREATE_POINT_INPUT structure is used by the mount manager to send a symbolic link name to a client that has requested symbolic link name by means of an IOCTL_MOUNTMGR_CREATE_POINT request.
MOUNTMGR_DRIVE_LETTER_INFORMATION The MOUNTMGR_DRIVE_LETTER_INFORMATION structure is used by the mount manager to furnish a drive letter to a client that has requested a driver letter by means of an IOCTL_MOUNTMGR_NEXT_DRIVE_LETTER request.
MOUNTMGR_DRIVE_LETTER_TARGET The MOUNTMGR_DRIVE_LETTER_TARGET structure is used by a mount manager client with an IOCTL_MOUNTMGR_NEXT_DRIVE_LETTER request to furnish a nonpersistent target device name to the mount manager.
MOUNTMGR_MOUNT_POINT The MOUNTMGR_MOUNT_POINT structure is used by mount manager clients in conjunction with an IOCTL_MOUNTMGR_QUERY_POINTS request to query the mount manager for all of the mount points (symbolic links) associated with a device.
MOUNTMGR_MOUNT_POINTS The MOUNTMGR_MOUNT_POINTS structure is used by mount manager to send a client the list of mount points associated with a device.
MOUNTMGR_TARGET_NAME The MOUNTMGR_TARGET_NAME structure contains the nonpersistent target device name for a device and is used by mount manager clients with the IOCTL_MOUNTMGR_KEEP_LINKS_WHEN_OFFLINE request to tell the mount manager to keep the symbolic link for a device active even after the device has gone offline.
MOUNTMGR_VOLUME_MOUNT_POINT The MOUNTMGR_VOLUME_MOUNT_POINT structure is used in conjunction with the IOCTL_MOUNTMGR_VOLUME_MOUNT_POINT_CREATED request to inform the mount manager that a volume mount point has been created.
