C++ Unit Testing and stubbing a 3rd party C library

I need to unit test some C++ objects that I've written that use a 3rd party C library. For reasons beyond the scope of this question, I can't call the 3rd party C library directly, and need to stub it out for the test suite.

For other parts of our unit test suite we use googlemock, but I don't think it can be used for C libraries. I can stub out the library manually, but prefer not to (partly due to laziness (its rather large), but mainly because its just a matter of principles).

So here's my question: is there a tool that generates stubbed code based on a C library header file? Once I have the stubbed-out code, I'll do some minor mods to it, then I'll link against it for the unit testing.

You cant wrap those calls in a class like described in http://code.google.com/p/googlemock/wiki/CookBook#Mocking_Free_Functions

Then You can inject (in dynamic or static way) this class and set expectation on it.

stubgen can generate stub members from header files, unless you have special requirements it should be able to do what you're looking for.
