You want to perform 1 buffer at a time, then read or write the buffer(s).  You can do one intermediate buffer at a time or one ksmps buffer (low-level buffer) at a time.

Thanks everyone.  Viktor: your comment made me go back and verify what I was linking against, I had incorrectly built the csnd library.  fixed.
ha!  so my next question is: if I use CppSound::Perform() is there a way to get access to the performance buffer?
again thanks for all of your help and patience.

Yes, I do this in AlgoScore and it works fine.
But I don't think it's correct to call csoundInitialize() after
csoundCreate()! In AlgoScore I call csoundInitialize(0,0,0) (once)
before I do anything else with csound.

static naRef f_create(naContext ctx, naRef me, int argc, naRef *args) {
   static cs_initialized=0;
   HostData *data;
   if(!cs_initialized) {
       csoundInitialize(0,0,0);
       cs_initialized=1;
   }
   data = (HostData*)malloc(sizeof(HostData));
   data->tag = NUMARG(0);
   data->graph_cb = naNil();
   data->outvalues = naNil();
   CSOUND *cs = csoundCreate((void*)data);
   return newCsoundGhost(ctx,cs);
}
