Callback objects in NT?

NTDEV
1

Hi All,
We are porting a driver from 2K to NT, which is a NDIS driver and has shared Callback Objects (for driver to driver communication). As there is no callback Object in NT, how our driver can speak to the next lower driver in NT? Can anyone please suggest some alternate methods of Driver to Driver communication in NT?

Thanks in advance,
Indira

IRP completions.
Passing a table of function pointers in IOCTL IRP.
Signaling events (the worst way, since is does not allow to pass a portion of data with the call).

Usually, the second way is used for tightly coupled drivers.
