io_uring_get_events(3)

✨ io_uring_get_events — flush outstanding requests to CQE ring ✨

okay bestie, welcome to io_uring_get_events(3), straight out of the liburing manual 💖 this one is short and sweet but it's lowkey important so don't skip it 🫶

🌸 SYNOPSIS 🌸

#include <liburing.h>

int io_uring_get_events(struct io_uring *ring);

💅 DESCRIPTION 💅

so what does io_uring_get_events(3) actually do? it runs outstanding work and flushes completion events to the CQE ring. that's the whole vibe. it's giving "cleanup era" ✨

now, when do you even have stuff needing to be flushed? two iconic scenarios, bestie:

• if the ring was full and had overflowed, there can be events just... sitting there, waiting to be flushed 💀
• OR, if the ring was set up with the IORING_SETUP_DEFER_TASKRUN flag, then this function will process outstanding tasks, which can possibly result in more CQEs showing up 👑

so yeah — deferred taskrun girlies, this is your moment. no cap. 🌈

🎀 RETURN VALUE 🎀

• success — returns 0. slay. 💖
• failure — returns -errno. not slay. 😭
