💅 iw_cm_accept(9) — like, the kernel API manual for iw_cm_accept, bestie 🎀

okay so real talk: this page lives in the Kernel API Manual, and the function it's hyping up is iw_cm_accept(9). yes the name is the same as the page, that's just how manpages do. sit down, grab a strawberry drink 🍓, we're learning how to accept an incoming connect request and honestly? iconic behavior.

✨ NAME ✨

iw_cm_accept — the function you call to accept an incoming connect request. that's it. that's the whole vibe. she says yes 💖

✨ SYNOPSIS ✨

int iw_cm_accept (struct iw_cm_id *cm_id , struct iw_cm_conn_param
*iw_param );

look at her. two params, returns an int, no cap. 🦋

✨ ARGUMENTS ✨

• cm_id — the IW CM identifier that's associated with the connection request 👑 this is the whole main character of the call.
• iw_param — a pointer to a structure that holds the connection establishment parameters. yep, all the setup details live in there 💅

✨ DESCRIPTION ✨

okay so here's the lore:

the cm_id you're passing in will have been provided in the event data for a CONNECT_REQUEST event — so like, you didn't just make it up, it came from the event 🫶

subsequent events related to this connection will be delivered to the specified IW CM identifier prior to — and may occur prior to — the return of this function. so yeah, prepare yourself, the events are already otw before you even get your return value 😭

and here's the important part, so listen up:

if this function returns a non-zero value, the client can assume that no events will be delivered to the specified IW CM identifier. like, zero. none. the connection request is a ghost 💀

so check that return value, bestie. always. 🌸
