mucse_poll_for_ack(9)

💌 mucse_poll_for_ack(9) — like, the kernel API manual, but make it make sense

okay so bestie, welcome to the mucse_poll_for_ack page 💅 this is a Kernel API Manual entry, and honestly? it's giving "small function, big responsibilities." no cap. let's get into it ✨

---

🌸 NAME 🌸

mucse_poll_for_ack — the function that just sits there and waits for a message acknowledgment 🫶 like it's refreshing the group chat waiting for someone to react to your text. lowkey relatable.

---

🦋 SYNOPSIS 🦋

int mucse_poll_for_ack (struct mucse_hw *hw );

that's it. one function, one argument, one job. simple queen behavior 👑

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💖 yeah, that's the whole description. it's the hardware struct, it's the main character, you hand it over and the function does its thing with it.

---

⭐ RETURN ⭐

• 0 — slay! ✨ it successfully received a message acknowledgment. everything worked, no notes, iconic.
• negative errno — not slay 😭 it did not successfully receive a message acknowledgment, and you get a negative errno back to tell you about it. read the code, bestie, it's telling you something.

💜 sign-off 💜

that's the whole page, bestie 🎀 it ships from ./drivers/net/ethernet/mucse/r... (the source string gets truncated in the footer, which is honestly such a mood 🙈), and it's dated October 2026 — yes, future girl summer. the function name and manual section, mucse_poll_for_ack(9), are right there in the footer too, holding it down like always 👑✨ 🌸🦋
