💅 rtrs_permit_to_clt_con(9) — the Kernel API Manual glow-up

okay so bestie, welcome to section 9 of the kernel API manual, and today's main character is rtrs_permit_to_clt_con. yes it's a long name. yes it's worth it. let's go 🫶

✨ NAME ✨

rtrs_permit_to_clt_con — returns the RDMA connection pointer by the permit. that's the whole vibe, no cap 💫

---

🌸 SYNOPSIS 🌸

struct rtrs_clt_con * rtrs_permit_to_clt_con (struct rtrs_clt_path
*clt_path , struct rtrs_permit *permit );

look at that signature. iconic. she takes two things and gives you back a struct rtrs_clt_con * 🔥

---

🎀 ARGUMENTS 🎀

• clt_path — the client path pointer. like, the path you're on, queen 👑
• permit — the permit for the allocation of the RDMA buffer. it's literally your permission slip for the buffer, iykyk 🎫

---

💜 NOTE 💜

okay this is the part where you pay attention, bestie, because it's giving important:

• IO connection starts from 1.
• 0 connection is for user messages.

so like, connection zero is not for your IO, she's for user messages. don't mix them up, fr fr 💀
