C ++中的unsigned short *和wchar_t错误

Question

I'm using VS2008 to make an C++ DLL for Fljs which is js used by Adobe Flash.

The hell function need an arg with type of unsigned short * used for register function name in js.

I use the sample successfully do some simple operations in js.It pass the arg use _T("functionname")

But the sample is C code.When I use C++ code(just change the .c to .cpp), VS tell me wchar_t is inner type, so I turn the option off and now the wchar_t is typedef of unsigned short.

Then compile it without error.But in js , it can't find the function name.

So I want to know why the js can't find the name? What had been done with the wchar_t which is both typedef of unsigned short in C and C++?

Answer 1

Most likely your function names are now mangled if you switch to C++ and don't flag the exported functions as C style.

You can see an explanation here on MSDN

What you can try is to make them C again.

extern "C" {  // only need to export C interface if

__declspec( dllimport ) void MyCFunc();

};
