💖 hinic_register_pf_mbox_cb — the Kernel API Manual, section 9 bestie ✨

Okay so real talk, this is a page from the Kernel API Manual, section 9, and it's all about one little function that does exactly one little job: it registers a mbox callback for pf. That's it. That's the whole vibe. 🎀

✨ NAME ✨

hinic_register_pf_mbox_cb — register mbox callback for pf

Like, literally just register that mbox callback, for pf. No cap. 🦋

🌸 SYNOPSIS 🌸

int hinic_register_pf_mbox_cb (struct hinic_hwdev *hwdev , enum
hinic_mod_type mod , hinic_pf_mbox_cb callback );

Look at her. Three args, one int return. Main character energy honestly. 👑

💅 ARGUMENTS 💅

  • hwdev — the pointer to hw device, bestie. That's your hardware device pointer, handing over the goods.
  • mod — the specific mod that the callback will handle. Like which module this callback is gonna be responsible for, iykyk.
  • callback — the callback function itself. The actual function. The whole point. 🫶

🔥 RETURN 🔥

  • 0 — success 🎉
  • negative — failure 😭
Lowkey important: it's 0 for the win, and anything negative means it did not slay. Check that return value, fr fr.

🌈 SEE ALSO 🌈
