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,
