💅 irdma_sc_add_mcast_grp — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of irdma_sc_add_mcast_grp(9) 💖 this is a kernel API manual page, and it's short but she's iconic — one function, two arguments, zero drama. let's get into it 🎀

🌸 NAME 🌸

irdma_sc_add_mcast_grp — allocates a mcast group entry inside ctx 🦋

like, that's the whole job. she adds the entry. she's the main character of multicast group setup. periodt ✨

---

⭐ SYNOPSIS ⭐

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

so she returns an int (iykyk) and takes two struct pointers — one for the context, one for the group info. keep the spacing exactly like that, we don't edit signatures in this house 🙈

---

💜 ARGUMENTS 💜

• ctx — the multcast group context 💫 (yes, that's how the page spells it, and honestly? she's quirky, we love her). this is the context the entry gets added into.
• mg — the multcast group info 🍓 all the details about the group itself live in here.

two args, no more, no notes. slay 💅
