Trying to invoke wintun using jnr-ffi, with zero knowledge of modern Cpp and jnr framework.

The first obstacle is figuring out wtf happened in c headers. I know you should define functions in headers. I expect soemthing like "int foo (int a, char *b);", but I got "typedef int(*FOO)(int a, char *b);", except there is no simple int and char as type, everything is micro.

After knowing I have no way to figure it out in a short amount of time, I decided to try jnr and see what I got.

But wintun is built for windows. The first function required a GUID, which has no official support in jnr.

Now it's 0130+0800. I decided to switch to jna (tomorrow, of course), which offers some win32 support. I don't care about performance anymore. As long as it works, I'm happy.

And I hope project Panama can go faster, so I don't have to go through this undocumented path. (JNR-FFI offers almost no documents, only basics, and those don't help)
