STD::DEFAULT_DELETE(3)

👑 std::default_delete< _Tp > — Library Functions Manual 💅

okay bestie, sit down, we're doing C++ memory management today and honestly? it's giving cleanup era. this little icon lives in the Library Functions Manual (libstdc++ girlies rise), and it's the thing that goes "and then we delete it" when your unique_ptr is done being the main character.

---

✨ NAME ✨

std::default_delete< _Tp > — no cap, that's the whole name, she's simple and she knows it 💖

---

🎀 SYNOPSIS 🎀

#include <memory>

🌸 Public Member Functions

• constexpr default_delete () noexcept=default — the default constructor, literally just vibing, does nothing, iconic ✨
• template<typename _Up, typename = _Require<is_convertible<_Up*, _Tp*>>> constexpr default_delete (const default_delete< _Up > &) noexcept — the converting constructor, she lets other deleters in conditionally (iykyk, more on that below 🦋)
• constexpr void operator() (_Tp *__ptr) const — the moment we've all been waiting for: it calls delete __ptr. periodt 💀

---

💜 Detailed Description

template<typename _Tp>
struct std::default_delete< _Tp >

so this is the primary template of default_delete, and her whole job description is: used by unique_ptr for single objects. not arrays. single objects. we're monogamous here 🫶

Since: C++11 ⭐ (she's been on the scene for a minute and she ate)

🧚 Constructor & Destructor Documentation

🌈 template<typename _Tp> std::default_delete< _Tp >::default_delete ()

[constexpr], [default], [noexcept]

Default constructor. that's it, that's the girl. she constructs and she defaults and she does it without throwing anything at you 😌

Fun lil note from the docs: Referenced by default_delete(). yes she references herself, it's called self-love, look it up 💅

---

🦋 template<typename _Tp> template<typename _Up, typename = _Require<is_convertible<_Up*, _Tp*>>> std::default_delete< _Tp >::default_delete (const default_delete< _Up > & )

[inline], [constexpr], [noexcept]

Converting constructor. this one is the social butterfly 🦋 — it lets you convert from a deleter meant for objects of a whole other type, _Up, but only if _Up* is convertible to _Tp*. if that conversion doesn't hold up? she's not letting you in. gatekeeping, but make it type-safe ✨

References default_delete().

🔥 Member Function Documentation

⭐ template<typename _Tp> void std::default_delete< _Tp >::operator() (_Tp * __ptr) const

[inline], [constexpr]

Calls delete __ptr. that's the entire plot of this function, no subplot, no side quest, we love a one-line queen 👑

⚠️ real talk, no jokes: this is the default deleter and it does exactly what it says — delete __ptr. the whole design is that unique_ptr owns a single object and this is what gets called when ownership ends. don't get cute with it.

and that's the whole page!! 🎀 mwah 💖 sending you off with the official sign-off: this came from the libstdc++ corner of the world, filed under that iconic truncated header std::defau...ete< _Tp >(3) — yes the man page literally shortens its own name, she's mysterious like that 💀✨ byeee, go free your pointers responsibly 🫶🌸
