✨ knav_queue_pop(9) ✨

okay so bestie, welcome to the knav_queue_pop page — it's from the Kernel API Manual and it's genuinely one of the simpler ones, so you're gonna eat this up 💅

---

🌸 NAME 🌸

knav_queue_pop — pop data (or descriptor) from the head of a queue 🎀

like… it takes the thing off the front of the line. head of the queue. first in, first out, classic main character behaviour 👑

---

🦋 SYNOPSIS 🦋

dma_addr_t knav_queue_pop (void *qhandle , unsigned *size );

that's the whole vibe. two args, one return, no drama ✨

---

🍓 ARGUMENTS 🍓

• qhandle — the hardware queue handle 💖 this is your little ticket to the queue you're messing with.
• size — (optional) the size of the data pop'ed. so if you wanna know how big the thing you just yanked out was, you pass this in. optional tho, no pressure 🫶

---

🔥 RETURN 🔥

DMA address on success, 0 on failure 🎯

so like… zero means it did not slay. check for that fr fr, don't just assume it worked 😭
