Okay, so I've gotten to the point where I want to call some of the 
methods in the library, and now I have found out that the library is 
written in C++.  My research indicates that I need to wrap the library 
with another C-based wrapper, but I can't find any suggestions on how to 
do that.  I've copied and translated the headers I'm using into C, and 
I've created an "fooImpl.cpp" file which will implement the C functions 
by calling the C++ functions, but it seems like a lot of work, and I'ld 
like some encouragment that I'm going down the right path before I spend 
hours and hours on this.

Anyways, a sample C++ function definition would be:
long CSyncRegisterConduit      (CONDHANDLE &) ;
And I've translated it into C as:
long CSyncRegisterConduit      (CONDHANDLE *) ;
And then my implementation would look like:
long CSyncRegisterConduit( CONDHANDLE* p1 ) {
     return SyncRegisterConduit( *p1 );
}

Does that look close to being correct?

Thanks,
Blake.
