PassThrough File System Minifilter Driver
The PassThrough minifilter demonstrates how to specify callback functions for different types of I/O requests.
Universal Windows Driver Compliant
This sample builds a Universal Windows Driver. It uses only APIs and DDIs that are included in OneCoreUAP.
Design and Operation
The PassThrough minifilter does not have any real functionality. For each type of I/O operation, the same pre and post callback functions are called. These callback functions simply forward the I/O request to the next filter on the stack.
