💖 NAME 💖

rio_release_outb_mbox — release outbound mailbox message service

okay so real talk, this is the little function that says "k bye" to an outbound mailbox message service and hands the keys back. that's the whole vibe ✨

---

🎀 SYNOPSIS 🎀

int rio_release_outb_mbox (struct rio_mport *mport , int mbox );

literally that's it. two args, one int coming back at you. slay 💅

---

🦋 ARGUMENTS 🦋

• mport — the RIO master port you're releasing the mailbox resource from, bestie. that's the one you're letting go of 🫶
• mbox — the mailbox number you wanna release. just tell it which one 📬

---

🌸 DESCRIPTION 🌸

So here's the tea: this releases ownership of an inbound mailbox resource. and yes, I know, the page is called outb and the description says inbound — I'm reading it to you exactly how it's written, no cap, not my job to fix it 🙈💀

Returns 0 if the request has been satisfied. that zero? that's the good ending, that's the main character energy ⭐

0

(that's the satisfied-request zero. iconic. ate. 🎀)
