I am writing some code that utilizes the TetGen library to find the convex hull of a set of points. However, by default 

tetrahedralize("Q", &in, &temp);

generates both the convex hull and the 3D Delaunay tetrahedralization. I am inclined to believe that it is possible to get only the convex hull as Mathematica has a working implementation of Tetgen and a corresponding function TetGenConvexHull[] that does so, but after going through the tetgen.cxx source code and documentation, I can't seem to find out how.

How can I modify the default behaviour of TetGen to only get the convex hull?

In short, you can not. TetGen (version 1.4.3) computes the delaunay tetrahedralization and from that the hull is extracted. What you can do is use the "E" option to not generate the *.ele. If you only need a convex hull, you may want to look at qhull and there the qconvex fucntion.
