Calling Pascal units

Have code written in Pascal in a unit format. Would like to call the units from C. I would appreciate a simple example of how to do this. Thanks , JSS

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

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.
