The free OSR Learning Library has more than 50 articles on a wide variety of topics about writing and debugging device drivers and Minifilters. From introductory level to advanced. All the articles have been recently reviewed and updated, and are written using the clear and definitive style you've come to expect from OSR over the years.

Would anyone know what is the expected behaviour of FltSendMessage / FilterGetMessage pair when the size of data sent (in FltSendMessage) is larger than the size of the buffer(s) provided by any I/O requests already pending (or initiated afterwards within the timeout) via FilterGetMessage? Is it documented at all, in the first place, or can it be inferred from general considerations about how I/O works? Or is it just one of those cases where it is not safe to try this, and one should always ensure that the buffer(s) provided by FilterGetMessage are large enough?
