> [c] Add parameter safety annotations for printf format strings

> Key: PROTON-2772
> URL: https://issues.apache.org/jira/browse/PROTON-2772
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Affects Versions: proton-c-0.39.0
> Reporter: Jiri Daněk
> Assignee: Jiri Daněk
> Priority: Major
> Fix For: proton-c-0.40.0

>
> There seem to be various mismatched printf format arguments. This is best
> resolved by annotating the string format parameters so that regular
> compilation warns on the mismatches as they happen.
> Proton already has some of this, but it is incomplete.
