alloc_wqes_shadow(9)

🌸 alloc_wqes_shadow(9) — the Kernel API Manual, bestie edition 🎀

okay so before we even start: this is a page from the Kernel API Manual, section 9 (that's the kernel-dev section, iykyk 💅). The star of the show is alloc_wqes_shadow, and she is literally here to hand out WQE shadows for a WQ. let's get into it 🦋

---

✨ NAME ✨

alloc_wqes_shadow — allocate WQE shadows for WQ

like... the whole personality is in the name, no cap. it allocates the WQE shadows. for the WQ. periodt 💖

---

✨ SYNOPSIS ✨

int alloc_wqes_shadow (struct hinic_wq *wq );

that's it, that's the whole signature. one function, one argument, returns an int. iconic minimalism ✨

---

✨ ARGUMENTS ✨

• wq — the WQ you want to allocate shadows for. that's her. that's the girl. she's a struct hinic_wq * and she needs her shadows 🫶

---

✨ DESCRIPTION ✨

so here's the tea ☕ — the return values are doing all the talking on this one:

• 0 — Success 🎉 slay, everything worked
• negative — Failure 😭 something went wrong, and the value is negative about it

that's genuinely it, bestie. no secret lore, no hidden caveats. you call it, you check the return, you move on. main character energy from start to finish 👑

✨ SEE ALSO ✨
