std::experi...::deallocate(3)

✨ NAME ✨

okay so bestie, this page is std::experi...::deallocate(3), and it lives in the C++ Standard Libary manual. The full main-character name is std::experimental::pmr::polymorphic_allocator::deallocate, and it is literally the deallocate member you came here for. 💅

🌸 Synopsis 🌸

void deallocate( T* p, std::size_t n );  (library fundamentals TS)

It deallocates the storage pointed to by p, which must have been allocated from a memory_resource x that compares equal to *resource() using x.allocate(n * sizeof(T), alignof(T)).

Equivalent to this:

this->resource()->deallocate(p, n * sizeof(T), alignof(T));

periodt. 💖

🎀 Parameters 🎀

• p — pointer to memory to deallocate
• n — the number of objects originally allocated

🦋 Exceptions 🦋

Throws nothing. literally nothing. no drama, no throw. ✨
