WDK Mini Filter Example
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.

For more information on file system minifilter design, start with the File System Minifilter Drivers section in the Installable File Systems Design Guide.
