rdma_set_reuseaddr(9)

🌸 NAME 🌸

Okay so welcome to rdma_set_reuseaddr(9), straight out of the Kernel API Manual 💖 — this is the function that lets you allow the reuse of local addresses when binding the rdma_cm_id. It’s giving “small but important” energy, fr fr. ✨

---

✨ SYNOPSIS ✨

The whole signature is literally this, bestie:

int rdma_set_reuseaddr (struct rdma_cm_id *id , int reuse );

---

🎀 ARGUMENTS 🎀

• id — the communication identifier you’re configuring. Like, this is the rdma_cm_id getting its little setting tweak. 💅
• reuse — the value that says whether the bound address is reusable. Simple as that. 🦋

---

💜 DESCRIPTION 💜

Okay, here’s the important part: reuse must be set before an address is bound to the id. That’s the rule. Before, bestie. Not after. No cap. ⭐

Set it up first, then bind. The order is the whole vibe check here. 🫶
