NAME

       io_uring_submit_and_wait_timeout  -  submit  requests to the submission queue and wait for
       the completion with timeout

SYNOPSIS

       #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);

DESCRIPTION

       The io_uring_submit_and_wait_timeout(3) function submits the next events to 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).

RETURN VALUE

       On success io_uring_submit_and_wait_timeout(3) returns the number of submitted  submission
       queue  entries.  On  failure  it  returns  -errno.   The  most  common failure case is not
       receiving a completion within the specified timeout, -ETIME is returned in this case.
