Qcap questions

[Andrew Talbot]

In qcap/pin.c, the function OutputPin_GetDeliveryBuffer() shows the
parameters tStart and tStop as being of type const REFERENCE_TIME *.
Looking at the SDK web site, I see a function called
CBaseOutputPin::GetDeliveryBuffer() that has similar parameters that are
non-const.

May I deconstify these parameters in our function, in order to avoid some
cast-qual warnings, or are they constrained?

Thanks,
