Ned Deily <n...@acm.org> added the comment: If you call ioctl with the mutate_flag True, you need to pass "an object supporting the read-write buffer protocol" as the arg parameter for the results of ioctl to be returned in. In your example, you pass a bytes object which is immutable. Try using a bytesarray object instead, which is mutable, or, for instance, an array object as shown in the documentation.
