Yes, that text is erroneous and a different method is being worked on.

Sorry for the inconvenience.

Subject: [wdmaudiodev] Vista APOs: new API calls for locking memory?

Hey there,

The SysFx document on developing APOs states:

        All code and data in the process path must be 
        nonpageable. The Windows Vista SDK contains a 
        new code- and memory-locking API that is useful 
        for this purpose. For details, see Nturtl.h.    


I'm having a hard time finding documentation on these new memory-locking
functions or the above-mentioned header, and the sample APO doesn't
allocate any memory.  Does anyone have pointers to these new functions,
documentation, and/or sample code? 

Thanks,

-andrew
