💅 drm_atomic_h...nector_state(9) — Kernel API Manual ✨

okay so first of all, bestie, the full name got truncated in the header (the terminal said no to that many characters), but the actual function is drm_atomic_helper_check_wb_connector_state, and we're about to get into it. This is the Kernel API Manual page for it. Buckle up 🎀

---

✨ NAME ✨

drm_atomic_helper_check_wb_connector_state — the vibe check for your writeback connector state 💖

---

🌸 SYNOPSIS 🌸

int drm_atomic_helper_check_wb_connector_state (struct drm_connector *connector , struct drm_atomic_commit *state );

---

🦋 ARGUMENTS 🦋

• connector — the corresponding connector, aka the connector that's the whole point of this, its moment, its main character era 👑
• state — the driver state object. yes that one. the state. it's giving "the driver's state object" 🫶

---

🎀 DESCRIPTION 🎀

so what this does is it checks whether the writeback connector state is actually valid, and if it isn't, it returns an error. that's the whole thing. it's a vibe check in function form, no cap 💅

---

⭐ RETURN ⭐

Zero for success, or -errno if it's not giving. literally the binary of moods 😭
