io_queue_release(3)

💖 io_queue_release — from the libaio girlies 💖

okay bestie, we're in the Linux AIO section of the manual (io_queue_release(3), she's a section 3 girlie, very library-call coded), and this one is literally the "we're done here, pack it up" function. let's get into it 🫶

✨ NAME ✨

io_queue_release — release the context associated with the userspace handle 💅

🌸 SYNOPSIS 🌸

#include <errno.h>
#include <libaio.h>

int io_queue_release(io_context_t ctx);

like yes, include both headers, that's the vibe, no cap ✨

🦋 DESCRIPTION 🦋

so io_queue_release destroys the context that's associated with the userspace handle. that's it, that's the whole job, she's a closer 🔥

and okay important: she may cancel any outstanding AIOs and block on completion. so if you've got stuff still in flight, this call might cancel it and then sit there waiting for it to finish. it's giving "we are NOT leaving until everyone's out of the pool" energy 😭 lowkey iconic of her.

💜 RETURN VALUES 💜

on success, io_queue_release() returns 0. periodt 💚

otherwise, -error is return — and yeah, the manpage literally says "is return", we're keeping that, it's part of the lore — where error is one of the Exxx values defined in the ERRORS section down below. so negative numbers, go look 'em up ⭐

🎀 ERRORS 🎀

• EINVAL — ctx refers to an uninitialized aio context, OR the iocb pointed to by iocbs contains an improperly initialized iocb. yeah she's calling you out, bestie 🙈
• ENOSYS — Not implemented. 💀 that's it. that's the whole entry. she's not here.

ngl bestie, if you're calling this, you already did the AIO thing and you're wrapping up. go you. main character energy 👑
