libie_ctlq_add(9)

🌸 NAME 🌸

okay bestie 💖 welcome to libie_ctlq_add(9) from the Kernel API Manual — this one is literally libie_ctlq_add — add one control queue. That's the whole vibe, no cap ✨

---

✨ SYNOPSIS ✨

struct libie_ctlq_info * libie_ctlq_add (struct libie_ctlq_ctx *ctx ,
const struct libie_ctlq_create_info *qinfo );

---

🎀 ARGUMENTS 🎀

• ctx — libie CP context information. It's giving context, bestie 🫶
• qinfo — information required for queue creation. The queue-creation intel, iykyk 💅

---

💅 DESCRIPTION 💅

okay so this function does the whole allocate-and-initialize combo for a control queue, then adds it to the control queue list. Main character queue-adding behavior, honestly 👑

🚨 prerequisite vibe check: libie_ctlq_init must be called prior to any calls to libie_ctlq_add. Like, do that first, fr fr — it's required, not a suggestion 😭

---

🦋 RETURN 🦋

On success you get the added control queue info pointer — slay 💖

On failure you get an error pointer — not slay, but that's the documented return, bestie 🙈
