__GNU_CXX::NEW_ALLOCATOR(3)

💖 __gnu_cxx::new_allocator< _Tp > — NAME 💖

okay bestie, welcome to the Library Functions Manual entry for __gnu_cxx:...ator< _Tp >(3), and let me just say — this one is giving allocator, but make it ✨classic✨.

So, the NAME of the whole thing: __gnu_cxx::new_allocator< _Tp > — an allocator that uses global new, as per C++03 [20.4.1]. That's it, that's the vibe. 🎀

---

✨ SYNOPSIS ✨

Pull it in like this, bestie:

#include <ext/new_allocator.h>

Oh and also? It Inherits std::__new_allocator< _Tp >. Yes, it's a nepo baby. And we love that for it. 💅

🌸 Public Types 🌸

the type list, no notes:

• typedef std::ptrdiff_t difference_type
• typedef std::true_type propagate_on_container_move_assignment
• typedef std::size_t size_type
• typedef _Tp value_type

🦋 Public Member Functions 🦋

here's what it can actually do:

• new_allocator (const new_allocator &) noexcept
• template<typename _Tp1> new_allocator (const new_allocator< _Tp1 > &) noexcept
• constexpr _Tp * allocate (size_type __n, const void *=static_cast< const void * >(0))
• constexpr void deallocate (_Tp *__p, size_type __n)

👑 Detailed Description 👑

okay so picture this:

template<typename _Tp>
    class __gnu_cxx::new_allocator< _Tp >

An allocator that uses global new, as per C++03 [20.4.1].

This is precisely the allocator defined in the C++ Standard. Like, the standard one. The blueprint. The main character. ⭐

• all allocation calls operator new
• all deallocation calls operator delete

That's the whole personality: new in, delete out, no cap.

and here's the tea 🍓 — this is a non-standard extension that can be used to guarantee allocation from new even if the library has been configured to use a different implementation for std::allocator. so if your libstdc++ got customized and you specifically need new, this is your girl. no guessing, that's literally what it's for.

🧚 Template Parameters 🧚

• _Tp — Type of allocated object. (that's the thing you're allocating, bestie. that's the whole parameter.)

Generated automatically by Doxygen for libstdc++ from the source code. so nobody hand-wrote this one, it just manifested.

and that's the page, periodt. 💅 this whole manual page came to you from libstdc++ (that's the source/version, bestie, straight off the footer), filed under __gnu_cxx:...ator< _Tp >(3), and it was auto-generated from the source code so you know it's fr fr accurate. mwah, go allocate something cute 🫶✨🎀
