QB_ATOMIC_POINTER_GET(3)

💖 QB_ATOMIC_POINTER_GET(3) 💖

okay bestie, so this is a page straight out of the libqb Programmer's Manual — yes, that libqb — and it's about one tiny function that does one tiny thing. but it's important, so pay attention, mkay? 🫶

---

✨ NAME ✨

qb_atomic_pointer_get — reads the value of the pointer pointed to by atomic.

like, that's it. that's the whole job. it reads a pointer. no cap. 👑

---

🌸 SYNOPSIS 🌸

#include <qb/qbatomic.h>

void * qb_atomic_pointer_get(
    volatile void *QB_GNUC_MAY_ALIAS   *atomic   /* a pointer to a void*. */
);

so you gotta #include <qb/qbatomic.h> first, obviously, or this whole thing is just giving undefined energy and we do not want that. 🙈

and look at that signature — it takes one arg and hands you back a void *. clean. minimal. iconic. 💅

---

🎀 PARAMS 🎀

• atomic — a pointer to a void*. yep. that's the whole parameter list. one single pointer, and you're pointing it at another pointer. pointers to pointers, it's giving pointerception fr fr. 🌀

---

🦋 DESCRIPTION 🦋

So basically: this reads the value of the pointer that atomic points at. that's the function. that's the vibe.

Also acts as a memory barrier. 🚧

which, bestie, is lowkey the whole reason you'd use this instead of just dereferencing and calling it a day. the memory barrier thing matters. don't skip it. ⭐

---

🌈 RETURN VALUE 🌈

the value to add to atomic.

ok so I know what you're thinking — "return the value to add?? on a get??" 😭 yeah. that's what the page says, word for word, and I am not about to start improvising on a manpage. I'm a good friend, not a compiler. take it as written and let the source code be your emotional support. 💀
