ttm_resource_manager_first(9)

💖 ttm_resource_manager_first — it's giving "start of the resource iterator" ✨

Okay bestie, we're in the Linux Kernel API Manual today, and this page is literally about ttm_resource_manager_first(9) — the glow-up that kicks off your whole loop over a resource manager's resources. Buckle up 🎀

---

✨ NAME ✨

ttm_resource_manager_first — no cap, this is the one that starts iterating over the resources of a resource manager. Main character energy for your for-loop 💅

---

🌸 SYNOPSIS 🌸

struct ttm_resource * ttm_resource_manager_first (struct
ttm_resource_cursor *cursor );

---

🦋 ARGUMENTS 🦋

• cursor — the cursor, bestie. It's the lil guy that records the position so you don't get lost in the sauce while iterating 🫶

---

🧚 DESCRIPTION 🧚

So here's the vibe: this function initializes the cursor and starts iterating. That's it, that's the whole moment ✨

⚠️ But listen — when you're done iterating, the caller must explicitly call ttm_resource_cursor_fini. Not "should", not "maybe", must. Don't leave your cursor hanging, it's not cute 😭

---

🔥 RETURN 🔥

The first resource from the resource manager. Literally the first one. You ate, first resource, slay 👑
