The main purpose of this method is to make code readable and to allow more secure compiler dependent implementations.

Remarks: The cast is currently performed through a c-style cast, since a static_cast or reinterpret_cast for the described purpose is not raises a compile error in Microsoft Visual Studio 2010.

The method returns NULL if the vector is empty.
