Logging in Export Driver

NTDEV
1

Hi All,
Logging in Kernel Drivers is achieved using IoWriteErrorLogEntry() &
IoallocateLogEntry().
The latter function requires a Driver object to allocate the error log
packet.

In case of an Export Driver, the DriverEntry() routine is not explicitly
called and hence a driver object is not allocated.

How is logging effected for such export drivers?

Thanks and Regards,
Subha

You need to have a PDEVICE_OBJECT or driver object around, otherwise you
cannot use these routines. You can get either from the user of the DLL.
