Making ColdFusion work with a C++ DLL

We have had a DLL written in C++ (called RealTimeProcess) for processing of speech for some years. We now need it to work in a web based environment and integrate with ColdFusion. The trouble is that The Dll expectes a pointer to the array of input data, and coldfusion cant manage pointers.? How can we make ColdFusion work with this .dll?
The solution can include modifying the dll, making a separate "wrapper" of some sort inbetween, as long as the resulting system works. Saving the parameters to from disk to communicate between the coldfusion and C++ to be used as a last resort.
## Deliverables
The solution is to contain changes to the source code of either/both the coldfusion script and the C++ dll to make it work. You may add an additional layer in between if necessary, but mention that in the bid.
A test file has been supplied, [url removed, login to view] that contains the raw input speech data as 16 bit integers.
The functions in the dll that require rewriting are the following:
voidSpeechAnalyseRT::storeAndAnalyseChunk(shortint* data, unsignedlongdataLength){
In this case, the int* pointer is the problem
And in the functions that return the results:
virtualconstdouble* CALL getVoicing() = 0; //size = umFrames
virtualconstint* CALL getCorr() = 0; //size = numFrames
virtualconstdouble* CALL getPitch() = 0; //size = *numFrames
ColdFusion needs to read these results, which it cant do at the moment with the data returned as pointers.
The solution must include:
Full source code,? and setup instructions needed to run? the solution.
The solution must achieve the goal of having ColdFusion read the data in [url removed, login to view], pass it into the RealTimeProcess dll, and read the results returned by the functions getVoicing etc successfully.
If other languages/technologies are needed, include this in the bid, + the cost of purchasing licenses if necessary.
The compiled .dll and source code is attached.
## Platform
Must work on any the following Windows platforms running coldfusion 8. Windows 2003 server, Windows XP, Windows Vista.
