None of the C/C++ compilers that I have worked with can access .TPU's as is.  You'll need to recompile the units as .OBJ files and add them to your project window.  Once that is done, you'll need to declare each prototype (function) as an external function with the EXTERN definition.

Be careful though -- Pascal handles function names, pointers, and strings rather differently than C does.  I'd recommend that you be aware of these differences prior to calling the functions because it CAN BE a hair-pulling experience.
