MOUNTMGR_DRIVE_LETTER_INFORMATION structure (mountmgr.h)

  • Article

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.

Syntax

typedef struct _MOUNTMGR_DRIVE_LETTER_INFORMATION {
  BOOLEAN DriveLetterWasAssigned;
  UCHAR   CurrentDriveLetter;
} MOUNTMGR_DRIVE_LETTER_INFORMATION, *PMOUNTMGR_DRIVE_LETTER_INFORMATION;

Members
