io_uring_unregister_ring_fd - unregister a ring file descriptor

 #include <liburing.h> 

 "int io_uring_unregister_ring_fd(struct io_uring *" ring ");" 

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)

Returns 1 on success, indicating that one file descriptor was unregistered, or -errno on error. io_uring_register_ring_fd (3), io_uring_register_files (3)
