Descriptions
Type
One of the predefined KOBJECTS types describing which Dispatcher Object this is.
Absolute
For a Timer, indicates if it is Absolute (that is to say, it expires at a given date and time) or Relative (it expires in a relative amount of time).
Size
Size in DWORDs of the Dispatcher Object.
Inserted
For a Timer, indicates if it has been inserted.
DebugActive
For a Thread, indicates if it's being debugged.
Lock
SignalState
The current Signal State of the Dispatcher Object. Usually 1 for Signaled and 0 for Not Signaled, but can be negative for Recursive Mutex and above 1 for Semaphores.
WaitListHead
Queue of waits outstanding on the current DISPATCHER_HEADER. Doubly-linked list of KWAIT_BLOCK.WaitListEntry
