So how are they filtered? ...


If we add flags=0 to above four APIs, we have to move the flags arguments to the last position in the arguments list because the rule "default arguments have to come after positional arguments." Changing them will break the binding
          APIs. so I didn't touch them.

...As I see you write "flags=0" for all the automatically generated
APIs here? And is there any risk to have other APIs of which flags
doesn't default to 0? Except the ones you mentioned in commit log.



       Yes,  I am not sure if the 0 is appropriatefor every APIs.
       I need more advice here.
       According to my test, they can accept the 0 value all.
