MOUNTMGR_DRIVE_LETTER_TARGET structure (mountmgr.h)

  • Article

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.

Syntax

typedef struct _MOUNTMGR_DRIVE_LETTER_TARGET {
  USHORT DeviceNameLength;
  WCHAR  DeviceName[1];
} MOUNTMGR_DRIVE_LETTER_TARGET, *PMOUNTMGR_DRIVE_LETTER_TARGET;

Members

DeviceNameLength

Contains the length, in bytes, of device name.

DeviceName[1]

Contains the nonpersistent target device name.

Remarks

The mount manager responds to the IOCTL_MOUNTMGR_NEXT_DRIVE_LETTER request by furnishing the client with a drive letter for the target device.

Nonpersistent target names must contain the full path of a target object name in the system object tree. For example: "\Device\HarddiskVolume1". For a discussion of the difference between drive letters and nonpersistent target device names, see Supporting Mount Manager Requests in a Storage Class Driver.
