[PATCH 3/5] bulk: Have object_child_foreach() take Error* and return boolean |
|
Date: |
Thu, 16 Feb 2023 13:25:22 +0100 |
Following the Error API best practices documented in commit
e3fe3988d7 ("error: Document Error API usage rules"), have the
object_child_foreach[_recursive]() handler take a Error* argument
and return a boolean indicating whether this error is set or not.
Convert all handler implementations.
