iavf_send_api_ver(9)

💅 iavf_send_api_ver(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's about iavf_send_api_ver, and honestly? she's a little diva with one job and she does it. ✨

---

🌸 NAME 🌸

iavf_send_api_ver —

(yeah the original page literally leaves this blank, no cap, so we're matching that energy 🫶)

---

🎀 SYNOPSIS 🎀

int iavf_send_api_ver (struct iavf_adapter *adapter );

so it hands back an int, takes one pointer, and that's the whole vibe check. iconic behavior, honestly.

---

🦋 ARGUMENTS 🦋

• adapter — the adapter structure. that's it, that's the whole arg. she just needs her adapter and she's good to go 💖

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — this function sends an API version admin queue message to the PF. that's the main character task. that's what she does. periodt.

the reply is not checked in this function. like, she sends the message and does NOT stick around to read the response. not her problem, not her shift 🙈 — if you want the reply handled, that's somebody else's function's job (see the SEE ALSO list, there are like forty of them lmao).

return values, bestie, listen up:

• returns 0 if the message was successfully sent 🎉
• returns one of the IAVF_ADMIN_QUEUE_ERROR_ statuses if it wasn't 😭

so like — 0 good, anything with that long IAVF_ADMIN_QUEUE_ERROR_ prefix means something went sideways. and remember: "successfully sent" does not mean "successfully replied to." she said what she said.

lowkey reminder: iavf_send_api_ver fires off the message and dips. the reply check lives elsewhere — don't come for her about it 🫶
