std::scoped...::deallocate(3)

hey bestie 💖 welcome to std::scoped...::deallocate(3) from the C++ Standard Libary man pages. yes, the title has ... in it and yes, we are keeping it exactly like that. let’s get into it 🫶

💖 NAME 💖

std::scoped_allocator_adaptor::deallocate — std::scoped_allocator_adaptor::deallocate

like, it’s literally the same thing twice. iconic behavior, no notes 💅

🦋 Synopsis 🦋

Defined in header <scoped_allocator>
void deallocate( pointer p, size_type n ) noexcept;  (since C++11)

so what’s the vibe? this one uses the outer allocator to deallocate the storage referenced by p, by calling:

std::allocator_traits<OuterAlloc>::deallocate(outer_allocator(), p, n)

that’s the whole move, fr fr. also notice that noexcept in the signature — that’s part of the whole look, don’t drop it ✨

🌸 Parameters 🌸

• p — pointer to the previously allocated memory 🫶
• n — the number of objects for which the memory was allocated

💀 Return value 💀

(none)

literally nothing comes back. the return value is giving invisible main character energy 🙈
