25 | * @brief Small macro that simplify references counting. | ||
26 | * | ||
27 | * References counting is not a difficult task, but you must | ||
28 | * handle it correctly every where, and that the issue. This | ||
29 | * set of macro do provide helper that will force to use the | ||
30 | * correct code in most case and reduce the bug likeliness. | ||
31 | * Of course this without affecting speed ! | ||
