Driver unloading.

NTDEV

Hi!

For example, we have a simple driver which can be unloaded dynamically.
Is it enough to send IRP_MJ_CLOSE from user mode to unload driver from memory
automatically? Unload routine is set.

Thanks.

Sergey.

No, use “net stop <your_driver>” instead. Also, you can use appropriate SCM
APIs. Note that driver unload routine is called only if driver isn’t
referenced i.e. all handles to its devices are closed.

No.

In NT4, call ControlService to stop it.
In w2k, use SetupDi functions to disable the devnodes controlled by it. It
will be unloaded when all devnodes are gone.
