NAME         top

       io_uring_unregister_ring_fd - unregister a ring file descriptor

SYNOPSIS         top

       #include <liburing.h>

       int io_uring_unregister_ring_fd(struct io_uring *ring);

DESCRIPTION         top

       io_uring_unregister_ring_fd(3) unregisters the file descriptor of
       the ring.

       Unregisters a ring descriptor previously registered with the
       task. This is done automatically when io_uring_queue_exit(3) is
       called, but can also be done to free up space for new ring
       registrations.  For more information on ring descriptor
       registration, see io_uring_register_ring_fd(3)

RETURN VALUE         top

       Returns 1 on success, indicating that one file descriptor was
       unregistered, or -errno on error.
