In the meantime, will the process crash, or just stall, if I use
pageable memory? I'm not able to tell anything special about the
process that would lend me to think that it's running at too high a
priority for the memory manager to interrupt it. Of course, I don't yet
know much about Vista...

We are still pondering on this.

Hakon, any progress? Outside of building and installing a driver that
allocates memory for our APO, I haven't found a way around this.

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
