qt_cacheline(3)

✨ qt_cacheline(3) ✨ — the libqthread era

okay bestie, so you know how CPUs don't fetch memory one lil byte at a time? they grab a whole chunk — a cache line — and if you don't know how big that chunk is, you're kinda just guessing. that's literally this whole function. it's in section 3 of the manual, it lives in libqthread, and it's tiny but it matters. 🎀

🌸 NAME 🌸

qt_cacheline — returns the cache line size 💅

🦋 SYNOPSIS 🦋

#include <qthread/cacheline.h>

int
qt_cacheline (void);

✨ DESCRIPTION ✨

so like. this function hands you back the size of the local machine's top-level cache line, measured in bytes. that's it, that's the whole vibe. 🫶

and the iconic part? it's calculated only once. one time. periodt. so you can call it as much as your little heart desires and it's not gonna go re-figure anything out for you — it already knows. 👑

💖 ngl this is one of those functions where the doc is longer than the work. lowkey obsessed. no cap.
