I haven't personally looked at it, but the thing to remember when writing
C++ that is going to be accessed from another language is that you usually
have to write C functions, and declare them as being WINAPI. You also have
to export them from your DLL. So a C function exported from a DLL for use
by another language might have the following prototype:
int WINAPI __declspec(dllexport) myExportedFunction(int param1, int param2);
I can't remember if the WINAPI is supposed to go before or after the
__declspec(dllexport), but if the above produces a compile error, you can
switch. Note that if you actually plan to do this yourself and link against
it, the dllexport has to be changed to dllimport when compiling the program
that links against the DLL, but since you're not going to do that, you can
just put dllexport in the code directly.
