💫 NAME 💫

update_planes_and_stream_adapter — send planes to be updated in DC, bestie ✨

---

🦋 SYNOPSIS 🦋

bool update_planes_and_stream_adapter (struct dc *dc , int update_type ,
int planes_count , struct dc_stream_state *stream , struct
dc_stream_update *stream_update , struct dc_surface_update
*array_of_surface_update );

okay so it returns a bool, it's got six whole arguments, and honestly? she's serving function signature realness 💅

🎀 ARGUMENTS 🎀

• dc — the Display Core control structure. this is the main character of the whole situation, no cap 👑
• update_type — tells you whether it's a FULL/MEDIUM/FAST update. pick your vibe, but like, pick it correctly 🙈
• planes_count — how many planes you're updating. the literal count. the number. the amount 💀
• stream — stream state. the stream's whole state of being, honestly 🌸
• stream_update — the stream update. yes bestie, it's a different thing from stream, they're both here, don't mix them up 🫶
• array_of_surface_update — a dc surface update pointer. it's an array, it's surfaces, it's updates, it's giving everything at once ✨

---

💖 DESCRIPTION 💖

okay so here's the tea: DC already has a generic way to update planes and stream — that's dc_update_planes_and_stream, and she's iconic, she does her job 👏

but DM might need some adjustments and preparation before calling it. like, DC can't just be ambushed, the vibes have to be right first, y'know? 🧚

that's literally what this function is for: it's a wrapper for dc_update_planes_and_stream that does any required configuration before passing control to DC. prep work first, then hand over the keys to the main character 🔥

so to recap: wrapper → does the setup → passes control to DC. periodt 💅
