slim_alloc_txn_tid(9)

💅 slim_alloc_txn_tid(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: you're deep in the Kernel API Manual (that's the manual name, iykyk) and you need a transaction ID for your SLIMbus message. That's literally this page. Welcome. 🦋

---

✨ NAME ✨

slim_alloc_txn_tid — Allocate a tid to txn 💫

Like, it hands your transaction a tid. That's the whole vibe.

---

🌸 SYNOPSIS 🌸

int slim_alloc_txn_tid (struct slim_controller *ctrl , struct
slim_msg_txn *txn );

That's the exact signature, no cap — copy it character for character or the compiler will absolutely come for you 😭

---

💖 ARGUMENTS 💖

• ctrl — Controller handle. This is your controller, your main character, the one holding it all together 👑
• txn — transaction to be allocated with tid. Yeah, this is the txn that's getting the tid. It's giving "the whole point of the function" energy fr fr.

---

⭐ RETURN ⭐

zero on success with valid txn->tid and error code on failures.

So like — zero? that's the slay case, and your txn->tid is valid and everything's cute ✨. Anything else is an error code, and you should probably go touch grass and, like, actually handle it 🙈

ngl the "valid txn->tid" part is doing a lot of work there — success means zero and a valid tid. Don't skip the vibe check on that one.
