lol

so it’s like a minefield

yep

so if you mix them up it breaks

close enough

and release is like unlocking it

so acquire is like locking the door

release fences prevent earlier stores from moving after the fence

acquire fences prevent later loads from moving before the fence

so what’s the difference between acquire and release fences

cool

just a function

no

so it’s not a class or anything

so it’s just a function call

ohhh

like std::atomic_thread_fence()

there’s an atomic fence function

so how do you actually use it

fair

because someone thought it was a good idea

so why does this exist

like most c++ features

just obscure

nope

so it’s not new

since c++11 i think

no it’s been around for a while

so is this like a c++20 thing

i dunno
