🌸 wx_read_mbx_pf(9) — the Kernel API Manual moment 💅

okay so bestie, welcome to wx_read_mbx_pf(9), straight out of the Kernel API Manual. this one is short and sweet and honestly kind of a whole vibe — it's the "read a message from the mailbox" girlie 🎀 and yes she does exactly what her name says.

✨ NAME ✨

wx_read_mbx_pf — Read a message from the mailbox 💌

like literally. you're grabbing a message out of the mailbox. that's the entire plot. no cap.

🦋 SYNOPSIS 🦋

int wx_read_mbx_pf (struct wx *wx , u32 *msg , u16 size , u16 vf );

that's the whole function signature, character for character, no edits from me 🫶

👑 ARGUMENTS 👑

okay so here's everyone invited to the function call party:

  • wx — pointer to the HW structure 🖥️ this is the hardware friend you're working with
  • msg — The message buffer 📨 this is where the message ends up living
  • size — Length of buffer 📏 how much room you've got to work with
  • vf — the VF index 🔢 yep, the VF index, that's the one

🌈 RETURN 🌈

return 0 on success and -EBUSY on failure 😭

that's the whole deal — 0 means slay, -EBUSY means nope. -EBUSY is literally in the manpage so don't come for me, that's just what it returns fr fr.
