Hi Dmitry Thank you for your review > > The return type and the variable of of_graph_get_endpoint_count() > > should be unsigned. Tidyup it. > > 'the variable'? > > I'd have added a few words telling that return type can be unsigned > because there is no error reporting for this function. I see. v4 will be Because of of_graph_get_endpoint_count() doesn't report error, just return count of endpoint, the return type of it should be unsigned. Tidyup it. Thank you for your help !!
