💌 wx_write_mbx_vf(9) — like, the kernel API manual, but make it cute

Okay bestie, so we're in wx_write_mbx_vf(9) territory — a little function living in the Kernel API Manual and she's here to write a message to the mailbox. That's it, that's the whole vibe. Main character energy for a mailbox write. 💖

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

That's the whole signature, copy-paste it exactly, don't be weird about it. 💅

🦋 ARGUMENTS 🦋

• wx — pointer to the HW structure. Your hardware bestie. The struct wx in question, iykyk.
• msg — The message buffer. This is where your message lives before it gets yeeted into the mailbox.
• size — Length of buffer. Gotta tell the function how much of msg to actually care about. Boundaries, queen. ✨
