C/C++

[Sean M. Tucker]

Hi,
I have a project to work on that was done in ANSI C... but I have some code
done in C++ that I can use. How can I use the C++ code in the C project?

(I'm using Visual Studio 6, but I wouldn't think it would matter if I was
using g++ or whatever)

Thanks.

If your C code takes no liberties, compile it as C++. (Any warnings or
errors you see are your fault. C permits many abuses that are not necessary
for good code.)

Under VC++, rename the files to .cpp and add them back to a project.

A C++ compiler/linker will compile/link both C and C++ code.

It's just a matter of somehow indicating to the compiler
that a.cpp is C++ and that b.cpp is C. Then, in your C++
code, make the function declarations as so:

extern "C" int Blah(int);


As for the C code calling C++ functions... no idea.
