Introduction

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.

The main goals of this library are: removing the needs for creating a cleanup function for every complex structure, providing a logical organization of allocated memory blocks and reducing the likelihood of creating memory leaks in long-running applications. All of this is achieved by allocating memory in a hierarchical structure of talloc contexts such that deallocating one context recursively frees all of its descendants as well.
