Edit description on GitHub

Windows Driver Kit DDI reference (ns-mountmgr-_mountmgr_target_name)

Description

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.

Members

`DeviceNameLength`

Contains the length, in bytes, of the device name stored in DeviceName.

`DeviceName`

Contains the nonpersistent target device name.

Remarks

Nonpersistent target names must contain the full path of a target object name in the system object tree. For example: "\Device\HarddiskVolume1".
