fn nop(self: *IO_Uring, user_data: u64) !*linux.io_uring_sqe

Queues (but does not submit) an SQE to perform a no-op. Returns a pointer to the SQE so that you can further modify the SQE for advanced use cases. A no-op is more useful than may appear at first glance. For example, you could call drain_previous_sqes() on the returned SQE, to use the no-op to know when the ring is idle before acting on a kill signal.

Parameters

self: *IO_Uring,
user_data: u64,
