QB_ATOMIC_POINTER_SET(3)

✨ QB_ATOMIC_POINTER_SET(3) ✨

okay bestie, so this is a page from the libqb Programmer's Manual, and it's about exactly one (1) little function that does exactly one (1) little thing. no drama, no chaos, just pointer assignment that's also a memory barrier. iconic behavior honestly. 💅

🌸 NAME 🌸

qb_atomic_pointer_set — sets the value of the pointer pointed to by atomic. that's it. that's the job. she does it flawlessly. 🎀

---

🦋 SYNOPSIS 🦋

#include <qb/qbatomic.h>

void qb_atomic_pointer_set(
    volatile void *QB_GNUC_MAY_ALIAS   *atomic,  /* a pointer to a void* */
    void                               *newval   /* the new value */
);

like look at her. two args. returns void. no notes. 🫶

🌈 PARAMS 🌈

• atomic — a pointer to a void*. so yeah, a pointer to a pointer. pointer-ception, lowkey. it's the thing you're aiming at. 🎯
• newval — the new value. the glow-up. what atomic is about to be pointing at. ✨

---

💖 DESCRIPTION 💖

so you hand it atomic (a pointer to a void*) and newval (the new value), and it sets the value of the pointer pointed to by atomic. simple. clean. slay. 🔥

and the little extra garnish on top: it also acts as a memory barrier. so it's not just an assignment — it's an assignment with main character energy that tells the compiler and the CPU to chill and order things properly around it. no cap. 🧚

fr fr, don't sleep on the memory barrier part. that's the whole reason you're using this instead of just assigning like a normal person. it's giving "trust the process." 💀
