QB_MAP_NOTIFY_DEL(3)

✨ qb_map_notify_del ✨

okay bestie, welcome to libqb's programmer's manual 💖 today we're doing qb_map_notify_del, and yes, the whole name is the vibe. it's a libqb thing, section 3 of the manual, so it's a library function. let's get into it 🫶

---

🌸 NAME 🌸

qb_map_notify_del — delete a notifier from the map. that's it. that's the job. breaking up with a notifier, no cap 💅

---

✨ SYNOPSIS ✨

#include <qb/qbmap.h>

int32_t qb_map_notify_del(
    qb_map_t         *m,       /* the map instance */
    /*
     * the key (or prefix) to attach the notification to.
     */
    const char       *key,
    qb_map_notify_fn  fn,      /* the callback */
    int32_t           events   /* the type of events to register for.*/
);

okay so first thing, you gotta pull in the header:

#include <qb/qbmap.h>

and then the function itself takes four things. four. count them. 👑

🎀 PARAMS 🎀

• m — the map instance. your map. the main character 🗺️
• key — the key (or prefix) to attach the notification to.
• fn — the callback.
• events — the type of events to register for.

---

🦋 DESCRIPTION 🦋

ngl, the original page just… leaves this one blank. not a single word. so there's literally nothing else the manpage says here, and i'm not about to make stuff up, bestie — that's not the move 🙈

---

💜 RETURN VALUE 💜

• 0 — success. slay. it worked ✨
• -errno — failure. it's giving negative errno energy 😭

---

⭐ NOTE ⭐

the key, fn and events must match those you added. fr fr. like, they have to be the exact same ones. no substitutions, no "close enough" — the notifier you're deleting has to line up with the one you put in there. remember that 💅
