CK_PR_FENCE_LOAD_DEPENDS(3)

💖 CK_PR_FENCE_LOAD_DEPENDS 💖

okay bestie, we're reading the manual for ck_pr_fence_load_depends(3), which lives in the Concurrency Kit (that's libck, link it with -lck) — yes she's fancy, yes she's real. sit down, grab a strawberry 🍓, we're doing barriers today.

✨ NAME ✨

ck_pr_fence_load_depends — a data dependency barrier 🦋

🎀 LIBRARY 🎀

Concurrency Kit — that's libck, and you link her with -lck. no cap. 💅

🌸 SYNOPSIS 🌸

#include <ck_pr.h>

void
ck_pr_fence_load_depends(void);

like… that's it. that's the whole function. she takes no args and returns nothing, she's just there, holding the vibe together. 👑

⭐ DESCRIPTION ⭐

so here's the tea ☕ — ck_pr_fence_load_depends(3) emits the necessary fences for pure data-dependent loads.

and rn? on every platform Concurrency Kit supports, she's only serving as a compiler barrier. just stopping the compiler from getting too creative with your instruction ordering. that's her whole job, she's doing it flawlessly, no notes. ✨

lowkey important warning bestie: unless you're on an architecture that actually re-orders data-dependent loads — like the defunct Alpha (rip bozo 💀) — this function is unnecessary. like, genuinely. you don't need her. she's iconic but she's not for you unless you're on ancient Alpha hardware, which, respectfully, you are not. 😭

🫶 RETURN VALUES 🫶

she has no return value. nothing. void. she gives you nothing back and honestly? that's the point. it's giving selfless queen energy. 🧚

and that's a wrap!! 🌈 this lil page came from the Concurrency Kit crew and was dated April 7, 2013 — the ck_pr_fence_load_depends(3) page, slaying since 2013, still just a compiler barrier, still unbothered, still ate. 💅✨ periodt. 🎀
