irdma_detach_mcast(9)

💅 irdma_detach_mcast(9) — Kernel API Manual ✨

Bestie, welcome to the irdma page where the whole job is detaching a qp from a multicast group. Short page, iconic energy, zero missing details. 🫶

---

💖 NAME 💖

irdma_detach_mcast — detach a qp from a multicast group. That's the assignment, and it ate. 💅

---

✨ SYNOPSIS ✨

int irdma_detach_mcast (struct ib_qp *ibqp , union ib_gid *ibgid , u16
       lid );

---

🌸 ARGUMENTS 🌸

Okay so there are exactly three arguments, and they are literally these:

• ibqp — ptr to qp. Yes bestie, that's the whole description: ptr to qp. 🎀
• ibgid — pointer to global ID ✨
• lid — local ID 🦋

---

🦋 DESCRIPTION 🦋

The DESCRIPTION is out here living its minimalist main-character life: it returns error status. That's it. That's the whole vibe. No extra lore, no secret paragraph, no “but actually also…” — just returns error status, periodt. 😭
