VOID CmpPostApc( struct _KAPC *Apc, PKNORMAL_ROUTINE *NormalRoutine, PVOID *NormalContext, PVOID *SystemArgument1, PVOID *SystemArgument2 ); Routine Description: This is the kernel apc routine. It is called for all notifies, regardless of what form of notification the caller requested. We compute the postblock address from the apc object address. IoStatus is set. SystemEvent and UserEvent will be signaled as appropriate. If the user requested an APC, then NormalRoutine will be set at entry and executed when we exit. The PostBlock is freed here. Arguments: Apc - pointer to apc object NormalRoutine - Will be called when we return NormalContext - will be 1st argument to normal routine, ApcContext passed in when NtNotifyChangeKey was called SystemArgument1 - IN: Status value for IoStatusBlock OUT: Ptr to IoStatusBlock (2nd arg to user apc routine) SystemArgument2 - Pointer to the PostBlock Return Value: NONE.
