i = TCgetRatio (h, hD, pratio)
where h short: board handle as issued by the
registerBoardEx function.
hD short: differential counter handle as issued by
the TCsetDiffCounters function.
pratio pointer to float: pointer to a 32-bit floating
point variable into which the value representing
the ratio of counts (Counter#2 / Counter#1) will
be placed.
Returns short: OK

TCsetDifferentialCounters. Call this function when finished with the differential counter.
i = TCfreeDiffCounters (h, hD)
where h short: board handle as issued by the
registerBoardEx function.
hD short: differential counter handle as issued by
