I am trying to create a plugin for CE, in the declaration of the functions to be exported I do something like "BOOL __declspec(dllexport) __stdcall CEPlugin_GetVersion(PPluginVersion pv, int sizeofpluginversion)".
But there is a Problem, the exported symbol is not "CEPlugin_GetVersion", in fact the symbol is"[email protected]@[email protected]@[email protected]".
How to make Visual Studio 2017 export the symbolos correctly?

1: You can name you sourcefile xxx.C instead of xxx.CPP
2: you can use a .def file to define the exports
3: (easiest) project properties->advanced->compile as->"compile as c code"

I tried to do step 1 and 4. But what I got now is that after the function name appears @x.
Example CEPlugin_GetVersion @ 8, where 8 is the number of bytes that the parameters of the function occupy.

MSDN Documentation on C name mangling

Use a .def file.
