STD::LOCK_GUARD(3)

💖 std::lock_guard< _Mutex > 💖

okay bestie, gather round, because we're talking about std::lock_guard< _Mutex > from the std namespace, and it lives in the Library Functions Manual. it's a simple scoped lock type. that's the whole vibe. simple. scoped. lock. periodt. 🎀

✨ NAME ✨

std::lock_guard< _Mutex > — a simple scoped lock type. no cap, that's literally the tagline.

---

🌸 SYNOPSIS 🌸

#include <mutex>

🦋 Public Types 🦋

• typedef _Mutex mutex_type — yeah so this is just _Mutex wearing a little name tag. that's the mutex type you're working with, bestie.

🎀 Public Member Functions 🎀

• lock_guard (const lock_guard &)=delete — copy constructor? deleted. you cannot copy this. not today, not ever. 💀
• lock_guard (mutex_type &__m) — the main character constructor. hand it a mutex reference and it locks it.
• lock_guard (mutex_type &__m, adopt_lock_t) noexcept — the "I already locked it myself, don't touch anything" constructor, marked noexcept.
• lock_guard & operator= (const lock_guard &)=delete — copy assignment? also deleted. assignment is NOT giving. 🚫

👑 Detailed Description 👑

template<typename _Mutex>
    class std::lock_guard< _Mutex >

a simple scoped lock type. 💅

so here's the tea: a lock_guard controls mutex ownership within a scope, and it releases that ownership in the destructor. that's it. that's the whole job. you make one, it owns the mutex for as long as it's alive, and the second it dies (scope ends, bye bye), the mutex gets released. RAII queen behavior honestly. 🔥

Since

C++11 — she's been iconic since 2011 and she's not slowing down. ⭐

heads up bestie: both the copy constructor and the copy assignment operator are =deleted, so if you try to copy a lock_guard the compiler will simply refuse. that's not a bug, that's the design, and it's protecting you fr fr. 🙈

and that's the whole page, babe — this was std::lock_...d< _Mutex >(3) from the libstdc++ girlies, delivered to you straight from the Library Functions Manual. thanks for coming to my ted talk, go forth and guard your scopes responsibly. mwah. 💖🎀🦋
