rdma_connect_locked(9)

🌸 rdma_connect_locked(9) — a Kernel API Manual moment 🌸

okay so bestie, welcome to the Kernel API Manual entry for rdma_connect_locked(9) — yes the (9) is part of the name, it's giving section-nine energy and we respect it 💅

---

✨ NAME ✨

rdma_connect_locked — literally just Initiate an active connection request. no cap, that's the whole vibe 🫶

---

🦋 SYNOPSIS 🦋

int rdma_connect_locked (struct rdma_cm_id *id , struct rdma_conn_param
*conn_param );

look at her. she returns an int, she takes two pointers, she's iconic 👑

---

🎀 ARGUMENTS 🎀

• id — the Connection identifier to connect. that's your main character right there, the thing you're actually connecting 🌟
• conn_param — Connection information used for connected QPs. all the deets your connected QPs need to know, packed up cute 🍓

---

💜 DESCRIPTION 💜

So she's Same as rdma_connect — same energy, same job — BUT (and this is the important part, don't skip it 🙈) she can only be called from the RDMA_CM_EVENT_ROUTE_RESOLVED handler callback.

fr fr, that's a hard requirement, not a suggestion. if you're not inside that handler callback, this is not your function, bestie. rdma_connect_locked is the locked one for a reason and we do not play with that 🔥
