iw_create_cm_id(9)

📦 version 7.3.1, in nixpkgs unstable

💅 iw_create_cm_id(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the RDMA/iWARP corner of the kernel and you need a whole new IW CM identifier to exist. That's literally this function's entire job. Welcome to iw_create_cm_id 🦋

✨ NAME ✨

iw_create_cm_id — Create an IW CM identifier. That's it, that's the whole vibe. She makes identifiers. 👑

🌸 SYNOPSIS 🌸

struct iw_cm_id * iw_create_cm_id (struct ib_device *device ,
       iw_cm_handler cm_handler , void *context );

Three args, one pointer back at you. Slay. ✨

🎀 ARGUMENTS 🎀

  • device — The IB device on which to create the IW CM identier. Like, this is the device she's gonna live on, no cap. 🖥️
  • cm_handler — User callback invoked to report events associated with the returned IW CM identifier. Basically your girl's phone number — when stuff happens to the id, this is who gets the call. 📞
  • context — User specified context associated with the id. Your own little bag of stuff, tied to the id, waiting for you to grab it later. 👜

🔥 SEE ALSO 🔥

ngl bestie, if you made an id you gotta clean her up later — that's what iw_destroy_cm_id(9) is for. Don't leave her hanging. 😭
