Date: 2009dec25 Language: C/C++ OS: Windows Platform: MSVC++ Q. How can I export a symbol (like a function name) from a DLL without a leading underscore in Visual Studio? A. Write your function like this:

extern "C" void _stdcall MyFunction(int param1, float param2) { // Body of your function goes here as usual. // No need for declaration in a header file. // Does not have to be type "void". // Can be "BOOL" or any simple type. // The parameters can be different than this. }

Add its name to your .def file:

EXPORTS MyFunction

This will export your function undecorated and without an underscore. Just as the Windows API functions are. I tried __declspec(dllexport) and other things but they always added a leading underscore or something.
