std::shared...utex::unlock(3)

omg hi bestie 💖 you’ve opened the std::shared...utex::unlock(3) page from the C++ Standard Libary manual (yes, that spelling is in the manual name, no cap 🙈).

🎀 NAME 🎀

std::shared_timed_mutex::unlock — literally std::shared_timed_mutex::unlock, that’s the name, that’s the whole vibe 💅.

🌸 Synopsis 🌸

void unlock();  (since C++14)

okay so this one unlocks the mutex. unlocked and unbothered, periodt ✨.

the mutex must be locked by the current thread of execution, otherwise the behavior is undefined. not “maybe fine”, not “we’ll see”, undefined — so like, respect the vibe check 🚨.

this operation synchronizes-with (as defined in std::memory_order) any subsequent lock operation that obtains ownership of the same mutex. that’s the whole synchronization plotline 💫.

🫶 Parameters 🫶

none, bestie — (none) 🍓.

🎀 Return value 🎀

also none — (none) 💖.

🦋 Exceptions 🦋

throws nothing. not a single throw, iconic 😌.

💅 Notes 💅

unlock() is usually not called directly: std::unique_lock and std::lock_guard are used to manage exclusive locking. so like, the wrappers are the main characters here, and unlock() is lowkey the supporting cast 🫶.
