>                 Key: DISPATCH-1783
>                 URL: https://issues.apache.org/jira/browse/DISPATCH-1783
>             Project: Qpid Dispatch
>          Issue Type: Improvement
>          Components: Tests
>    Affects Versions: 1.14.0
>            Reporter: Jiri Daněk
>            Priority: Major
>
> During the work on https://github.com/apache/qpid-dispatch/pull/684, there 
> was at one point a version of the PR, which tested what happens if 
> {{vsnprintf}} called from {{safe_snprinf}} returns {{-1}}.
> This was done by replacing the {{vsnprintf}} with a mock (technically it's 
> probably a stub, or maybe fake, but let's ignore the proper terminology).
> There are various possibilities how to approach mocking in C. They are less 
> nice than in more dynamic languages such as Java, or even C++ (where it's 
> possible to subclass things). Nevertheless, it can be useful technique, and 
> it should be explored.
