Leveraging C++20/23 Features for Low Level Interactions - Jeffrey Erickson - CppCon 2024
---

Low level interactions are a core part of embedded implementations. All too often, C++ developers rely on C constructs and interactions due to prior biases around language support. Herein we present effective leveraging of C++20 and C++23 constructs in an embedded driver code base. From using an existing C driver more effectively with modern C++ smart pointers to leveraging constexprs for bit and byte manipulation in the standard library, we will go over how you can stay on the cutting edge of the C++ language evolution in the embedded space.

CppCon is the annual, week-long face-to-face gathering for the entire C++ community. The conference is organized by the C++ community for the community. You will enjoy inspirational talks and a friendly atmosphere designed to help attendees learn from each other, meet interesting people, and generally have a stimulating experience. Taking place this year in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts.

7:13 - well, the get() will return the pointer by value, so the next call to it will return the same pointer by value. Of course the my_c_api() can change the data pointed by that pointer. But it can't change the pointer stored inside the smart pointer via the get() --> because it gets that as a copy.

The my_c_api() can still delete the pointed memory though leading to disaster.

44:02 alignas(4) ? before each field in the data structure, will manage individual field alignment for small padding amounts with items of different sizes

There are a lot of things wrong. The speaker talks about unique pointer but i would use reference because the base address is static

Isn't the use of volatile discouraged?
