ib_close_qp(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, this is ib_close_qp(9) from the Kernel API Manual — manual name folded in near the top just like you asked 💖. The vibe is simple and iconic: ib_close_qp means release an external reference to a QP. That's it. That's the whole main-character job.

✨ SYNOPSIS ✨

no cap, here's the exact signature:

int ib_close_qp (struct ib_qp *qp );

🎀 ARGUMENTS 🎀

  • qp — the QP handle you're releasing. That's the one. 🫶

💅 DESCRIPTION 💅

So the caller releases the opened QP handle. Easy.

But listen: the underlying shared QP is not destroyed until all internal references are released. The way that works is lowkey important — your external ref is just one little string, and the shared QP stays alive while other internal refs are still holding on. No cap. 💀

bestie, do not assume closing your external reference nukes the shared QP. It does not. The shared QP waits for all internal references to be released first. Periodt.
