Guys,

quick question - got a function like:

void CalculateApproach(float (&Params)[4], double (&ObjectPos)[3], double
(&VehiclePos)[4], double (&NewPos)[4])

OK, the seconds argument should come from an array but this array is
bigger than the expected 3 i.e it has 10 elements but I only need 4,5 and
6 so I tried something like:

CalculateApproach(fAppParams, &dFeatures[4], dCurVehPos, dNewVehPos);

Calculateapproache( float&* fAppParams, double& dFeatures[4], double&*
dcurVehPos, double&* dNewVehPos )

but it fails for me. Am I trying to do something that is not allowed and
hence should just make new array[3] and copy my values in and then pass it
into the function or can someone give me hint towards the syntax i should
be using if it can work?

Cheers,

John.
