io_uring_submit_and_wait_timeout - submit requests to the submission queue and wait for the completion with timeout
#include <liburing.h> int io_uring_submit_and_wait_timeout(struct io_uring *ring, struct io_uring_cqe **cqe_ptr, unsigned wait_nr, struct __kernel_timespec *ts, sigset_t *sigmask);
The io_uring_submit_and_wait_timeout(3) function submits the next requests from the submission queue belonging to the ring and waits for wait_nr completion events, or until the timeout ts expires. The completion events are stored in the cqe_ptr array. The sigmask specifies the set of signals to block. The prevailing signal mask is restored before returning. 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_timeout(3).
On success io_uring_submit_and_wait_timeout(3) returns the number of submitted submission queue entries. On failure it returns -errno. Note that in earlier versions of the liburing library, the return value was 0 on success. The most common failure case is not receiving a completion within the specified timeout, -ETIME is returned in this case.
