Thread: 'wrapping' code

what is meant exactly by the term wrapping code?
-that is in the context of intergrating code from another language?

let me explain my problem:

i am building a system in C++ in a modular fashion (as should be).
To this end i need to integrate the (entire) functionality of a small but related set of programs written in C. Each console executable uses the same header files & these contain a lot of globals which i want to keep away from the rest of my system. Each program in effect takes command line parameters, a couple of files, and outputs numerical results to std out.

Ideally, i would like to wrap these programs into a class, and rename each main() in each program as a separate function. This would save me writing code to make a system call to run each executable...

...but the header files:

what options do i have? is the above possible? what are the most common approaches to this problem? i'm a complete newbie with this stuff, so any pointers of comments of any kind would be well received.
I'm on a tight deadline too, so what's the quicj=kest thing i can do here?

thanks

Don't worry people, i've just worked out a way to do it and it doesn't even require so much as an extern "c"....

...ah the beauty of the ANSI C & C++ standards!...

whatever did people do before standardization?
i guess i'll never know

>whatever did people do before standardization?

Perhaps create their own variant of C so it fits their needs and so that someone else his/her compiler cannot compile it.
