If you're storing the boolean *in* the pointer (i.e. the pointer *is* the boolean)
then I think you mean:
FrmSetGadgetData(pForm, nGadgetIndex, (void *)boolValue);

In your case, you won't be getting a pointer *to* a Boolean, you'll be getting a
pointer which *is* a Boolean:
if (pBoolVal) {
// do something
}

You could, but that would be very wasteful for a Boolean, since the overhead of
allocating dynamic memory for 1 byte far exceeds 1 byte.
