idpf_send_get_rx_ptype_msg(9)

💅 idpf_send_get_rx_ptype_msg — bestie, it's a (9) Kernel API page 💅

okay so this is a page from the Kernel API Manual, section 9 — aka the land of kernel functions — and today's main character is idpf_send_get_rx_ptype_msg. grab a lil snack 🍓, we're talking virtchnl and packet types.

---

🎀 NAME 🎀

idpf_send_get_rx_ptype_msg — literally just "Send virtchnl for ptype info". that's the whole vibe. it sends a virtchnl message to go get the ptype info. iconic, focused, no notes 💅

---

✨ SYNOPSIS ✨

int idpf_send_get_rx_ptype_msg (struct idpf_adapter *adapter );

look at her go 🦋 one argument, returns an int, very demure.

---

🌸 ARGUMENTS 🌸

• adapter — the driver-specific private structure 🫶 like, it's the adapter's own lil secret stash of driver data. you hand it over and she does the thing.

---

⭐ RETURN ⭐

• 0 on success 🎉 slay, everything worked
• negative on failure 😭 not slay, but at least she tells you

ngl bestie, "negative on failure" is the whole spec — no cap, that's exactly what it says. don't go inventing specific errno values, that's not in the source ✨
