Since it perhaps will be next version, I have few style comments here
(ignore them if you are not going to send a new version by some other reasons).

I think it's better to put it one line below.

+ blank line?

After this change it seems we may drop temp_out and use out instead.

We may also join these together, though it's up to you.

Perhaps move it after next line, or before previous one.

We may skip this change, but if we go with it, better to place before
'int ret;' line.

I would group each of these with relative group of definitions above.

Maybe writable_trip_count -> writable_trip_cnt? (in align with r/o one).
