That's correct

// This is in the AUPublic code in the SDK - AUInputElement.cpp
Here's how we call it:
theResult = reinterpret_cast<AudioUnitRenderSliceProc>(mConnRenderProc)(
mConnInstanceStorage, ioActionFlags, &inTimeStamp,
mConnection.sourceOutputNumber,
&pullBuffer->mBuffers[0]);
You CANNOT pass in a NULL reference for the render flags for a V2 AudioUnit
- clearly documented even!
