vdec_msg_queue_dqbuf(9)

💅 vdec_msg_queue_dqbuf — the "gimme my buffer back" era

okay bestie, welcome to the Kernel API Manual ✨ this one's a tiny little function with main character energy — it lives over in the kernel and it does exactly one thing: it takes a lat buffer off the queue list. that's it. that's the whole vibe. 🎀

---

🌸 NAME 🌸

vdec_msg_queue_dqbuf — dequeue lat buffer from queue list. literally what it says on the tin, no plot twist 💖

---

✨ SYNOPSIS ✨

struct vdec_lat_buf * vdec_msg_queue_dqbuf (struct vdec_msg_queue_ctx
*ctx );

so it takes one argument, hands you back a struct vdec_lat_buf *, and yes, that pointer is doing the heavy lifting 🫶

---

🦋 ARGUMENTS 🦋

• ctx — the message queue context. that's the whole thing. that's the entire argument list. she's lowkey minimal and we stan 🎀

---

💜 RETURN 💜

returns not null if the dq (dequeue, bestie, keep up 😭) went successfully — or, you know, fail. and that's the official story 💀

so real talk: success gives you a non-null struct vdec_lat_buf *, and anything else is the fail case. plan accordingly, king 👑
