io_uring_submit_and_wait - submit requests to the submission queue and wait for completion
#include <liburing.h> int io_uring_submit_and_wait(struct io_uring *ring, unsigned wait_nr);
The io_uring_submit_and_wait(3) function submits the next requests from the submission queue belonging to the ring and waits for wait_nr completion events. After the caller retrieves a submission queue entry (SQE) with io_uring_get_sqe(3) and prepares the SQE, it can be submitted with io_uring_submit_and_wait(3).
On success io_uring_submit_and_wait(3) returns the number of submitted submission queue entries. On failure it returns -errno.
