📦 version 7.3.1, in nixpkgs unstable

💅 iw_cm_init_qp_attr — a kernel API moment (section 9, bestie)

okay so first things first, the manual name is iw_cm_init_qp_attr(9) and it lives in the Kernel API Manual — that's the whole vibe of this page, we're in kernel-API territory now 🧚

✨ NAME ✨

iw_cm_init_qp_attr — literally the function you call to initialize the attributes of the QP that's associated with an IW CM identifier. that's it, that's the whole job 🎀

🌸 SYNOPSIS 🌸

int iw_cm_init_qp_attr (struct iw_cm_id *cm_id , struct ib_qp_attr
*qp_attr , int *qp_attr_mask );

yup, it returns an int, and yup, there are exactly three args. no cap, that's the signature, copy it character for character or the compiler will be like "girl what" 😭

🦋 ARGUMENTS 🦋

  • cm_id — the IW CM identifier that's associated with the QP. like, the little ID card that tells you which QP we're even talking about 💳
  • qp_attr — pointer to the QP attributes structure. this is where the attributes actually live, you're just handing over the address 🫶
  • qp_attr_mask — pointer to a bit vector specifying which QP attributes are valid. key word: valid. it's the mask, it's telling you which of the attribute slots are actually real and not just vibes 🌈

👑 SEE ALSO 👑

bestie the crossover episode is real, here's the whole friend group:

that's eleven references plus a header file, and yes you should read them, they're all main character energy in their own way 💜

hot tip: nothing else on this page — no environment variables, no exit statuses, no bug notes, no examples. sometimes a manpage is short and iconic and that's fine 💅

and that's the tea 🍓 this page comes from ./include/rdma, dated October 2026, and the title is of course iw_cm_init_qp_attr(9) — slay, go initialize some QP attributes, you've got this 🔥💖
