💅 vdec_msg_que...lat_buf_full(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the Kernel API Manual 💖 and today's main character is vdec_msg_queue_wait_lat_buf_full(9) — yes the header is long, yes it's truncated, we love her anyway 🎀

✨ NAME ✨

vdec_msg_queue_wait_lat_buf_full — the little function whose whole job is checking whether all lat buffer in lat list 🦋

like. that's it. that's the vibe check. is the lat list full of lat buffers or not 🌸

---

🌈 SYNOPSIS 🌈

bool vdec_msg_queue_wait_lat_buf_full (struct vdec_msg_queue *msg_queue
);

one argument, one bool coming back at ya 🫶 no cap.

---

🎀 ARGUMENTS 🎀

• msg_queue — used to store the lat buffer information 💜 so yeah, hand her the struct that holds all the lat buffer deets and she'll go look inside it, iconic behaviour honestly 👑

ngl the wording is literally the original's word salad — success gives you true, otherwise it's fail, and that's the whole story bestie 😭 no extra lore, don't @ me 💀

like, init, init_ctx, qbuf, dqbuf, update both the rptr and wptr, deinit — the full lifecycle slay 💅 and wait_lat_buf_full right here is literally checking if the lat list is full before any of that proceeds, periodt 🍓
