Solution 1

You need to prefix the function name with extern "C".
Normally an exported function without name mangling would look like this -

extern "C" __declspec(dllexport) int MyFunction(int, int);

The export could also be done using a .DEF file instead of specifying __declspec(dllexport).

I am already using that. However, that still decorates the name with a leading underscore. i.e. Foo() becomes _Foo. How do I loose that leading Underscore.

The Microsoft compilers add these name decorations to distinguish between different calling conventions.
The __cdecl calling convention does not add this decoration.
If you want to export without using these decoration irrespective of the calling convention, you must export the functions using a DEF file instead of using __declspec(dllexport).

Solution 2

The only way to remove decorations completely is through def files.
