💅 ionic_queue_empty — the manual page, but make it make sense

okay so bestie, welcome to ionic_queue_empty(9) from the Kernel API Manual — yes, that's the manual name, we're being fancy today ✨ this is the little helper that peeks at a queue and tells you if it's got nothing in it. empty. void. no thoughts, head empty, queue empty 🫶

🌸 NAME

ionic_queue_empty — test if queue is empty

like. is it empty. that's the whole job. and she does it slayfully 💅

✨ SYNOPSIS

bool ionic_queue_empty (struct ionic_queue *q );

one function, one argument, returns a bool. short and iconic, no notes 👑

🎀 ARGUMENTS

  • q — Queue structure. yep, that's the queue you're vibe-checking. hand her over and she'll tell you what's up 💖

🦋 DESCRIPTION

okay so here's the tea, and it's important: this is only valid for to-device queues.

literal. only. to-device. queues. do not go pointing this at any old queue and expecting main character behaviour from it — it's giving "specific use case only" and we respect the boundaries 🙈

⭐ RETURN

is empty — that's what you get back. whether it's empty or not. is empty. that's the return value, bestie, fr fr 🌈

👑 SEE ALSO

the whole friend group, all here, all linked, all iconic:

go read them. they ate. 🔥

ngl if you're calling this on a queue that isn't a to-device queue, bestie, put the keyboard down and re-read the DESCRIPTION. i'm saying it with love 💜
