My suggestion would be to get a copy of:
GCC: The Complete Reference
Arthur Griffith
McGraw-Hill Osborne Media
ISBN 978-0072224054
This is discussed in the chapter on "Using the Compiler Collection".
It basically tells you how you have to define Objective C wrappers for
the Objective C code you want to call from C so that it can be lined
with the C to provide C wrappers.

Hi, Terry,
I'm interested in writing such a binding. Definitely it'll be the
first binding that I write for Mac! :)
But don't know if it's also useful in other cases or for somebody
else. And I need to learn how to do it...
OK, what I need to write a C/C++ binding? I have a powerbook g4,
with tiger and xcode installed, and firefox for sure. What else?
Best regards,
Calvin
