Testing 'C' functions

[LJ Kyle Brost]

Hello,

I'm developing on a project that is mixed C/C++ and I'm trying to figure out how to write test cases for C functions.  I've looked at the Cookbook and I cannot see how to do this.  Could someone give me some pointers?

Thanks,

What doesn't make sense?  If I had mixed C/C++, I'd still write the tests in CppUnit/C++, just assert that the returns from the extern "C" functions were as I expected.

I should have been more specific in my message.  Attached is a sample of code that has a class and a simple function.  The 'main' contains a runner for the class.

My question is, How do I register the test_IsEven_* functions with CppUnit and have it automatically execute and collect the results?

Thanks,
