In today's post, I will explain one of C++'s biggest pitfalls: reinterpret_cast. Another title for this post could be: This is not the cast you're looking for!
What reinterpret_cast doesn't do
Andreas Fertig
From the article:
My motivation for this blog post comes from multiple training classes I thought over the past several months and a couple of talks I gave. Since C++23, you have a new facility in the Standard Library:
std::start_lifetime_as. When teaching class with a focus on embedded environments or presenting talks with such a focus, I started to addstd::start_lifetime_asto the material. With an interesting outcome.The feedback I get is roughly:
- why do I need
std::start_lifetime_as, I already havereinterpret_cast?- why can I use
reinterpret_cast?If you never heard of
start_lifetime_asplease consider reading my post, The correct way to do type punning in C++ - The second act.
