irdma_sc_del_mcast_grp(9)

💖 irdma_sc_del_mcast_grp — the Kernel API Manual moment 🎀

okay bestie, so this one is from the Kernel API Manual, and it's literally the "breakup" function for multicast groups. no cap, it's giving "you're not on the list anymore, bestie" energy 💅

---

✨ NAME ✨

irdma_sc_del_mcast_grp — Delete mcast group 🗑️

Like, it deletes the multicast group. That's the whole vibe. Periodt.

---

🌸 SYNOPSIS 🌸

int irdma_sc_del_mcast_grp (struct irdma_mcast_grp_info *ctx , struct
irdma_mcast_grp_ctx_entry_info *mg );

Two structs walk in, one int walks out. That's the plot 🫶

---

🦋 ARGUMENTS 🦋

• ctx — the multicast group context 🧚 the environment, the setting, the stage where this whole thing goes down.
• mg — the multicast group info 🌈 the actual details of the group you're trying to yeet.

---

👑 DESCRIPTION 👑

So here's the tea ☕: irdma_sc_del_mcast_grp finds a specific multicast group inside the context and removes it. That's it, that's the function.

But — and this is the important part, don't skip it — all parameters must match in order for a multicast group to actually get removed. Every single one. Like, this is a strict "name, address, and star sign all have to line up" kind of situation 😭 no partial matches, no "close enough", no vibes-based removal. It's an exact-match breakup, fr fr.

bestie if your params don't all line up, you're just gonna stand there looking cute and the group stays. match them all or it's not happening 💀
