!slist

  • Article

The !slist extension displays a singly-linked list (SList).

!slist Address [ Symbol [Offset] ] 
!slist -?

Parameters

Address
Specifies the address of the SLIST_HEADER.

Symbol
Specifies the data type to use for display. If Symbol is specified, the debugger will assume that each node of the SList is an instance of this data type when displaying it.

Offset
Specifies the byte offset of the SList pointer within the structure.

-?
Displays some brief Help text for this extension in the Debugger Command window.

DLL

Exts.dll

Remarks

If you know the nature of the linked structures, the Symbol and Offset parameters are very useful. To see the difference, here are two examples; the first omits the Symbol and Offset parameters, while the second includes them.
