__GNU_CXX::MALLOC_ALLOCATOR(3cxx)

💖 NAME 💖

__gnu_cxx::malloc_allocator< _Tp > — an allocator that uses malloc. bestie. that's literally it. that's the whole vibe.

(this page lives in section 3cxx of the manual, iykyk 💅)

✨ SYNOPSIS ✨

#include <malloc_allocator.h>

🌸 Public Types 🌸

• typedef std::ptrdiff_t difference_type — the type you use for distances between pointers, standard-issue 🎀
• typedef std::true_type propagate_on_container_move_assignment — yes, this container does propagate on container move assignment, her little true_type said so 💅
• typedef std::size_t size_type — the type for sizes and counts, classic
• typedef _Tp value_type — the thing being allocated is _Tp, main character energy 👑

🦋 Public Member Functions 🦋

• constexpr malloc_allocator (const malloc_allocator &) noexcept — copy constructor, constexpr, noexcept, zero drama ✨
• template<typename _Tp1 > constexpr malloc_allocator (const malloc_allocator< _Tp1 > &) noexcept — the converting copy constructor, so you can build one from an allocator of a different type _Tp1. also constexpr, also noexcept. slay
• _Tp * allocate (size_type __n, const void *=0) — hands you back _Tp *. takes __n and a second const void * argument that defaults to 0. this is where the malloc happens 🍓
• void deallocate (_Tp *__p, size_type) — gives the memory back. takes the pointer __p and a size. this is where the free happens 🧚

🎀 Friends 🎀

• template<typename _Up > constexpr bool operator== (const malloc_allocator &, const malloc_allocator< _Up > &) noexcept — the equality comparison between two malloc_allocators, and it's templated on _Up so the two sides can be different types. constexpr, noexcept, friendship confirmed 🫶

⭐ Detailed Description ⭐

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

"An allocator that uses malloc." — that's the official tagline, no notes.

This is precisely the allocator defined in the C++ Standard. like, the actual one. no cap.

• 💀 all allocation calls malloc
• 💀 all deallocation calls free

and that's the entire personality. lowkey iconic, highkey simple.

bestie did you catch that — allocation = malloc, deallocation = free, exactly as the Standard defines. no extra spice, no hidden behaviour, just the two C functions doing their thing.

okay that's the whole page, mwah 💜 — this cutie was generated automatically by Doxygen for libstdc++ from the source code, and it's serving __gnu_cxx::malloc_allocator< _Tp > from the 3cxx section of the manual. go forth and allocate responsibly ✨🎀🦋
