Author: nobounce <steffen.winter@proton.me> Date: Wed Jul 26 16:19:17 2023 +0200 Use nullptr instead of NULL. See https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf TLDR: NULL is of type int and relies on proper implicit pointer conversion which may lead to issues when using overloaded functions It is also considered a 'best practise' for modern C++ and conveys the programmers intention more precisly. commitd53307f14c
