Returns short: Differential counter handle (>= 0). Use this handle as the hD
parameter in calls to TCgetDiffCount, TCgetRatio and
TCfreeDiffCounters when referring to this particular differential
counter pair.

6.4.6.2 Read Differential Count — TCgetDiffCount
Reads the difference between the count values of the two counters specified in the
TCsetDiffCounters function.
i = TCgetDiffCount (h, hD, pdiff)
where h short: board handle as issued by the
registerBoardEx function.
hD short: differential counter handle as issued by
the TCsetDiffCounters function.
pdiff pointer to long: pointer to a long integer
variable into which the 16-bit count value
representing (Count#2 – Count#1) will be
placed.
Returns short: OK

6.4.6.3 Read Differential Ratio — TCgetRatio
Reads the ratio of the count values of the two counter/timers specified in function
TCsetDiffCounters.
