How to create C code using Mathlink

Question

I have studied examples of using mathlink from Visual Studio. The question is, I have a mathematica notebook file where the needed calculations are done. Now I want to make the same things but from my C program using Mathlink. Is there an automatic tool for converting the Mathematica notebook file to C code so that they will be called by using the mathlink?

Is there an automatic tool for converting the Mathematica notebook file to C code so that they will be called by using the mathlink?

The closest to an automatic conversion that I am aware of is using Compile with CompilationTarget -> "C" in Mathematica version 8.

This is probably not what you want however, because it will require rewriting your code in a way that it can be handled by Compile. Further, it is automatically linking the function rather than embedding it in an external program.
