Paged pool memory or nonpaged pool memory ??? (Windows driver development)

Question

I am new to Windows driver development. I just want to know that a global variable in the driver will use paged pool memory or nonpaged pool memory?

Thanks and Regards

Answer 1

It depends. A non-paged pool should be reserved for memory that should remain in RAM, so if you are doing something critical that will be affected by a page of memory from a disk operation, then use non paged.

See here for more details .

Answer 2

NonPagedPool.
