Note  Third party network driver developers are not expected to manually use this extension command. You can run it to see the information it displays but you are not able to reuse the details it provides in your driver.

The !ndiskd.ndisslot extension displays the contents of an NDIS per-processor variable. If you run this extension with no parameters, !ndiskd will display a list of all NDIS per-processor variables on the system.

!ndiskd.ndisslot [-handle <x>] [-itemtype <str>]

Parameters

-handle
Handle of the slot.

-itemtype
Type of the value stored in the slot.

DLL

Ndiskd.dll

Examples

Run the !ndiskd.ndisslot extension with no parameters to see a list of all per-processor slot variables. The following example output has excised the middle portion of the list for brevity.

1: kd> !ndiskd.ndisslot
    Per-processor slot                     Summary of contents

    ffffc804ae060918 - NDtk                All values are zero
    ffffc804ae060920 - tsR                 All values are non-zero
    ffffc804ae060928 - NDrw                All values are zero
    ffffc804ae060930 - NDtk                All values are zero
    ffffc804ae060938 - NDtk                All values are zero

    ffffc804ae060948 - NDtk                All values are zero
    ffffc804ae060950 - NDrw                All values are zero
    ffffc804ae060958 - NDrw                All values are zero

    Statistics

Clicking on one of the handles for the per-processor slot variables will show you the details for that variable. The following example uses the handle ffffc804ae060920 for the tsR variable, from the previous example.

1: kd> !ndiskd.ndisslot ffffc804ae060920
    Processor          Slot value

    01                 00000006
    02                 00000006
