QB_ATOMIC_INT_ADD(3)

💖 qb_atomic_int_add — bestie edition 💖

okay so real quick, this is qb_atomic_int_add(3) from the libqb Programmer's Manual, section 3, and honestly? it's giving "tiny function, big responsibilities." let's get into it 🫶

---

✨ NAME ✨

qb_atomic_int_add — atomically adds val to the integer pointed to by atomic.

like, atomically atomically. no cap. 🧚

---

✨ SYNOPSIS ✨

#include <qb/qbatomic.h>

void qb_atomic_int_add(
    volatile int32_t QB_GNUC_MAY_ALIAS   *atomic,  /* a pointer to an integer */
    int32_t                               val      /* the value to add to *atomic */
);

bestie look at that signature. two args. no return value. it just does the thing. main character energy fr fr 👑

---

✨ PARAMS ✨

• atomic — a pointer to an integer. that's the lil guy getting the addition done to it 💅
• val — the value to add to *atomic. yes it goes into the pointer target, not the pointer itself. iykyk 😭

---

✨ DESCRIPTION ✨

so it adds val to the integer that atomic points at, and it does it atomically — which means nobody can sneak in halfway and catch it mid-addition. no half-finished math, no cursed in-between state. gorgeous. flawless. iconic. 🌸

also it acts as a memory barrier 🧱✨

that's the whole description. short king behavior but like, in a good way.
