When filesystems are dismounted?

OSR_Community_UserOSR_Community_User Member Posts: 110,217
Hi, All

I'm writting disk driver for NT4 based on RamDisk sample . At ShutdownDispatch I want delete all device objects
I create that represent logical drives. I know that if I delete device while filesystem is still mounted on it
will lead to bad things. How can I be sure that filesystems are dismounted from my devices?
If they are not dismounted on ShutdownDispatch, how can I dismount them, or I need to delay
deletion of device objects?

Regards, Dennis

    Filesystems are dismounted by one of the FSCTL functions. It must be in
    IRP_MJ_FILE_SYSTEM_CONTROL path.
