NAME
       io_uring_unregister_ring_fd - unregister a ring file descriptor

SYNOPSIS
       #include <liburing.h>

       int io_uring_unregister_ring_fd(struct io_uring *ring);

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