__GNU_CXX::THROW_ALLOCATOR_BASE(3)

✨ __gnu_cxx::throw_allocator_base< _Tp, _Cond > ✨

okay bestie, so this is a page from the libstdc++ manual (a Library Functions Manual, iykyk) and it's all about a little allocator with big main character energy 💅

---

🌸 NAME 🌸

__gnu_cxx::throw_allocator_base< _Tp, _Cond > — the allocator class with logging and exception generation control. It's literally designed to be used as an allocator_type inside templatized code. no cap 💖

---

🎀 SYNOPSIS 🎀

#include <throw_allocator.h>

So first things first: it inherits __gnu_cxx::annotate_base. slay.

And it gets inherited by:

• __gnu_cxx::throw_allocator_limit< _Tp1 >
• __gnu_cxx::throw_allocator_random< _Tp1 >

the family tree is giving legacy, honestly 🦋

👑 Public Types 👑

all the lil type names, here they are, exactly as they are:

• typedef const value_type * const_pointer
• typedef const value_type & const_reference
• typedef std::ptrdiff_t difference_type
• typedef value_type * pointer
• typedef std::true_type propagate_on_container_move_assignment
• typedef value_type & reference
• typedef std::size_t size_type
• typedef _Tp value_type

eight of them. iconic. periodt ✨

💖 Public Member Functions 💖

here's the whole roster, every single one, no skipping:

• const_pointer address (const_reference __x) const noexcept
• pointer address (reference __x) const noexcept
• pointer allocate (size_type __n, const void *__hint=0)
• void check (size_type __n)
• map_alloc_type::iterator check_allocated (void *p, size_t size)
• void check_allocated (pointer __p, size_type __n)
• void check_constructed (size_t label)
• map_construct_type::iterator check_constructed (void *p)
• template<typename _Up, typename... _Args> void construct (_Up *__p, _Args &&... __args)
• void deallocate (pointer __p, size_type __n)
• template<typename _Up> void destroy (_Up *__p)
• void erase (void *p, size_t size)
• void erase_construct (void *p)
• void insert (void *p, size_t size)
• void insert_construct (void *p)
• size_type max_size () const noexcept

look at all those little functions, bestie. they're thriving 🌈

• static void check ()
• static size_t get_label ()
• static void set_label (size_t l)

static besties, standing on their own, lowkey iconic 💜

🧚 Detailed Description 🧚

template<typename _Tp, typename _Cond>
    class __gnu_cxx::throw_allocator_base< _Tp, _Cond >

"Allocator class with logging and exception generation control. Intended to be used as an allocator_type in templatized code."

that's the whole vibe, fr fr 🔥

Note: Deallocate not allowed to throw.

like, deallocate simply is not permitted to throw. it's not that kind of function. it does not have the range. 🙈

and that's the whole page bestie, we ate that 🍓

okay so the sign-off: this whole thing comes from the libstdc++ manual, generated by Doxygen for libstdc++ straight from the source code, and yes, that's the version and the source right there — no extra date on this one, the footer was just repping libstdc++ and the __gnu_cxx:...Tp, _Cond >(3) page name. mwah 💅
