ib_destroy_cq(9)

💅 ib_destroy_cq

okay so bestie, welcome to the Kernel API Manual (section 9, we love a legend) 💖 — today's main character is ib_destroy_cq, and honestly? It does exactly one thing and it does it iconically. No cap. 🎀

✨ NAME ✨

ib_destroy_cq — destroys the specified kernel CQ. That's it. That's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

void ib_destroy_cq (struct ib_cq *cq );

literally just hand it a CQ bestie and it's gone ✨

🎀 ARGUMENTS 🎀

• cq — the CQ to destroy. the one you're sending to the shadow realm. give it here 💅

⚠️ NOTE ⚠️

okay important bestie, listen: for a user cq, use ib_destroy_cq_user with a valid udata! Do not come for this function with a user cq, i'm begging 😭 — different tool for that job, fr fr.
