AV/C Streaming Protocol Driver Function Codes

The AV/C Streaming filter driver intercepts IRPs on their way down the device stack.

To communicate with avcstrm.sys, subunit drivers must set their IRP's IoControlCode member to IOCTL_AVCSTRM_CLASS.

To make I/O requests, include the header file avcstrm.h, which is included with the Microsoft Windows Driver Kit (WDK).
