NAME        top

       io_uring_wait_cqes_min_timeout - wait for completions with both       batch and normal timeout

SYNOPSIS        top

#include <liburing.h>int io_uring_wait_cqes_min_timeout(struct io_uring *ring,struct io_uring_cqe **cqe_ptr,unsignedwait_nr,struct __kernel_timespec *ts,unsigned intmin_wait_usec,sigset_t *sigmask);

DESCRIPTION        top

       Theio_uring_wait_cqes_min_timeout(3) waits for completions from       the submission queue belonging to thering and waits forwait_nr       completion events, or until the timeoutts expires. The completion       events are stored in thecqe_ptr array. If non-zero,min_wait_usec       denotes a timeout for thewait_nr batch.       Thesigmask specifies the set of signals to block. If set, it is       equivalent to atomically executing the following calls:           sigset_t origmask;           pthread_sigmask(SIG_SETMASK, &sigmask, &origmask);           ret = io_uring_wait_cqes_min_timeout(ring, cqe, wait_nr, ts, min_wait, NULL);           pthread_sigmask(SIG_SETMASK, &origmask, NULL);       This works likeio_uring_submit_and_wait_min_timeout(3) except       that it doesn't submit requests. See that man page for a       description for how the min timeout waiting works.       Available since 6.12.

RETURN VALUE        top

       On successio_uring_wait_cqes_min_timeout(3) returns the 0.On       failure it returns-errno.  If the kernel doesn't support this       functionality,-EINVALwill be returned. See note on the feature       flag.  The most common failure case is not receiving a completion       within the specified timeout,-ETIMEis returned in this case.
