Load/Unload Kernel Mode DLL

NTDEV
1

Hi All,

I create a kernel mode DLL (EXPORT_DRIVER). It doesn’t explictly export any
functions. It calls to a registration routine provided by another export
driver to register it’s entry points. How can I find a way to load or unload
the dll driver on demand?

Thanks,
JT

If it doesn’t have any exports it probably shouldn’t be an export_driver.
Make it a regular driver and have it call your other driver, then you can
load it in the normal maner. There routines ZwLoadDriver and ZwUnloadDriver
that will allow a driver to be loaded, but even there you better have a
proper driver, and not the kludge you described.

ZwLoadDriver/ZwUnloadDriver will solve my issue. Thank you very much.
