Our client's SQL/SDK programmer is looking to code in a language other than C# and asked us to ask you if you have header files for the CR.dll.  Below is further information about what he is looking to do.

I am looking to code some of these importation systems in ECL/C/CL, if I can, and to get the FFI set up without a ton of brute-force guesswork, the headers would be helpful.

They don't provide any information about their implementation of the code, so I am not asking them to divulge any trade secrets. The headers only provide the name, and most importantly, the signatures of the functions they have written in C/C++. I already have the names of the methods, I just need the signatures. This includes the return values, whether they are pointers of values, or not...
