rdma_set_afonly(9)

🌸 NAME 🌸

okay so this is rdma_set_afonly(9) from the Kernel API Manual, and she’s here to specify that listens are restricted to the bound address family only. that’s the whole assignment, bestie — no cap, it’s iconic 💅✨

✨ SYNOPSIS ✨

this is the exact signature, character for character — slay:

int rdma_set_afonly (struct rdma_cm_id *id , int afonly );

🎀 ARGUMENTS 🎀

• id — Communication identifer to configure. yes, “identifer” with that spelling — we keep the lore 🫶
• afonly — Value indicating if listens are restricted. it’s literally the value that says whether listens are restricted or not 👀

💅 DESCRIPTION 💅

this one must be set before the identifier is in the listening state — lowkey that’s the entire rule. like, set it early, bestie, before the identifier is in the listening state. periodt. ⏰💀
