I'm porting some code from cpp and I'd like to know what means (void)debugDraw; in the following?

void	SphereTriangleDetector::getClosestPoints(const ClosestPointInput& input,Result& output,class btIDebugDraw* debugDraw,bool swapResults)
{
	(void)debugDraw;
        ....
}

I haven’t seen that particular construct before, but it looks to me like a no-op.

Basically it's done to avoid compiler warnings about unused parameters.
