Still not working, but I took the latest patch and: - rebased it against libnbd 1.0 - fixed it so it handles new args and cbargs The generator now runs without warnings. This patch doesn't handle optargs at all. In C these are converted to non-optional parameter. Rust doesn't (AFAIK) have optional or labelled arguments unfortunately. Rich.

Use <0 for errors, 0 for normal state, and >0 for clean completion. In future this would be necessary if it's decided to make partiter a generic lib (similar to disklib) - though it has to be quieted first and provide strerr()-like functionality in place of its verbosity. diff --git a/com32/chain/chain.c b/com32/chain/chain.c index ae95d45..c08ec6e 100644 --- a/com32/chain/chain.c +++ b/com32/chain/chain.c @@ -352,7 +352,7 @@ int find_dp(struct part_iter **_iter) } while (!pi_next(iter)); /* broken part st...

This small set fixes few bugs, improves gpt handling (under buggy conditions) and implements strict flag with more fine grained control which should fix issues with sanity checks against disk sizes. If this set is allright I'd want to do what I mentioned in older discussion with Ady - backport missing patches from 6.x to 5.x and 4.x so all versions have up to date chain version. Michal
