💖 std::declare_no_pointers(3) — C++ Standard Libary 💖

🌟 NAME 🌟

std::declare_no_pointers — okay bestie, it's literally the function std::declare_no_pointers, chillin' in the C++ Standard Libary. That's the whole name section, no cap.

✨ Synopsis ✨

So this icon is defined in header <memory>, and the signature is giving:

Defined in header <memory>
void declare_no_pointers( char *p, std::size_t n );  (since C++11)
                                                      (removed in C++23)

It informs the garbage collector or leak detector that the specified memory region — n bytes beginning at the byte pointed to by p — contains no traceable pointers. If any part of the region is within an allocated object, the entire region must be contained in the same object. Periodt. 🫶

🎀 Parameters 🎀

• p — pointer to the beginning of the range
• n — the number of bytes in the range

🌸 Return value 🌸

• (none) — literally no return value, bestie. 💅

💀 Exceptions 💀
