std::pointer_safety(3)

🎀 NAME 🎀

std::pointer_safety — std::pointer_safety. Yep, the name line is literally the same thing twice, and honestly? iconic. This is the C++ Standard Libary page for the std::pointer_safety(3) manual entry, so buckle up bestie, we're doing pointer safety modes.

✨ Synopsis ✨

          Defined in header <memory>
          enum class pointer_safety {

               relaxed,                (since C++11)
               preferred,              (removed in C++23)
               strict

          };

The scoped enumeration type pointer_safety lists the pointer safety modes supported by C++. That's the whole vibe check. 💅

🌈 Enumeration constants 🌈

• pointer_safety::strict — okay so only safely-derived pointers (pointers to objects allocated with new or subobjects thereof) may be dereferenced or deallocated. Garbage collector may be active. Strict is strict, bestie, no cap. 💀
• pointer_safety::preferred — all pointers are considered valid and may be dereferenced or deallocated. A reachability-based leak detector may be active. This one is marked (removed in C++23) up in the synopsis, so yeah, it's giving legacy energy. 🦋
• pointer_safety::relaxed — all pointers are considered valid and may be dereferenced or deallocated. Chill mode activated. 🌸

• get_pointer_safety — returns the current pointer safety model. It's marked (C++11), it's a (function), and it's (removed in C++23). The way this little reference is doing the most. 👑✨

Later, bestie! 💖 This was served fresh from http://cppreference.com on 2024.06.10 for the std::pointer_safety(3) page. Mwah 💋
