Thank you for your interest.  Welcome to the community.

Helping the general community is my hope with this project.

Excellent.

This is an excellent point.  OpenAFS does not have a favorite
testing framework.  It is something that OpenAFS sorely needs.
A set of tests for each function that test both expected success
and failure cases would be an excellent addition to this project.

Since StrSafe doesn't exist on Linux, it isn't possible to make use
of the library on that platform which is why I suggested a Windows
specific change.  However, another approach would be to implement
some of the simpler functions (String{Cb,Cch}{Copy,Cat}A) to show
an example of your coding style and quality.

You can submit it to OpenAFS via GSoC and the OpenAFS GSoC mentors
can provide you private feedback on it via socghop.
