💅 ionic_queue_consume(9) — Kernel API Manual, but make it make sense

okay bestie, so this is a page from the Kernel API Manual (9 = kernel section, iykyk) and it's literally about bumping the consumer index like it's the easiest thing in the world. Which, tbh, it kind of is — but there's one big gotcha and we're gonna get into it. 🫶

✨ NAME ✨

ionic_queue_consume — increase the consumer index ✨

Like, that's it. That's the whole job. She consumes. She moves the index. Iconic behaviour, no notes.

🌸 SYNOPSIS 🌸

void ionic_queue_consume (struct ionic_queue *q );

void return, one single argument, very low-drama function signature. We stan a no-nonsense API. 👑

🎀 ARGUMENTS 🎀

  • q — the queue structure 💖 literally the queue bestie, that's the whole thing, hand over your struct ionic_queue * and let her cook.

🦋 DESCRIPTION 🦋

so the function does one (1) thing: it increases the consumer index. main character energy, zero side quests. 🌈

but — and I need you to hear me on this — the caller must ensure that the queue is not empty. It is not checked here. Not even a little bit. No vibe check, no guard clause, nothing. 🙈

⚠️ fr fr: if you call this on an empty queue, that's on you. The function will not warn you, will not protect you, will not save you. You are the check. You are the safety net. 😭

also, and this is lowkey important: this is only valid for to-device queues. to-device only. not the other kind. don't try it on the other kind. 💀

💜 SEE ALSO 💜

the whole friend group, in the order the manpage lists them, no cap:

like, go read ionic_queue_empty(9) before you call this one, bestie, I am begging you. 🧚 it's right there. it's literally right there. ✨

and that's the page!! 💅✨🎀🦋🌸🫶
