The sscan record in synapps does that ... if you are looking for an example.  It "double buffers" the collected data allowing a client more time to access it.

From sscanRecord.c:
if (precPvt->validBuf == B_BUFFER) {
      paddr->pfield = precPvt->detBufPtr[group].pBufB;
} else {
      paddr->pfield = precPvt->detBufPtr[group].pBufA;
}

Well how about that.  This is just what I was thinking.  I had assumed that simply overwriting pfield would cause problems.  I'll definitely take a close look at this code.

Thanks,
Michael
