fsl_get_inb_message(9)

💌 fsl_get_inb_message — yeah that's her, she's from the Kernel API Manual bestie, page 9 of the fsl_get_inb_message saga 🎀

Ok so like, hi, welcome to the fsl_get_inb_message(9) glow-up 💅 this is the little function that goes and grabs you a message off the MPC85xx message unit's inbound queue. She's giving short but iconic, no cap.

✨ NAME ✨

fsl_get_inb_message — fetch an inbound message from the MPC85xx message unit 🦋

Like, that's literally her whole job. She fetches. She's inbound. She's a message. Slay.

---

🌸 SYNOPSIS 🌸

void * fsl_get_inb_message (struct rio_mport *mport , int mbox );

Yes the return type is void * and yes that's a little unhinged of her but we love her anyway 😭

---

🎀 ARGUMENTS 🎀

• mport — the master port that's implementing the inbound message unit ✨ she's the main character here, the whole port situation
• mbox — the inbound mailbox number 🧚 just tell her which mailbox, she'll handle the rest

---

💖 DESCRIPTION 💖

Okay so bestie, here's the tea ☕ — fsl_get_inb_message gets you the next available inbound message from the inbound message queue. That's it. That's the vibe. 🫶

And what do you get back? A pointer to the message on success 🔥 — or NULL on failure 💀. That's the whole drama. Like, she either pulls through with the message or she gives you the void. No cap.

So fr fr: check for that NULL, because she will not warn you, she will just hand you nothing and move on with her day 🙈
