Comments:       Talloc is a hierarchical, reference counted memory pool system with destructors.
                It is built atop the C standard library and it defines a set of utility functions that
                altogether simplifies allocation and deallocation of data, especially for complex
                structures that contain many dynamically allocated elements such as strings and
                arrays.
