Use of uv__udp_finish_close is Unix specific

[nkolban]

There is a reference to a function called uv__udp_finish_close() ... see:

libtuv/source/uv_run.c

Line 68 in 65b4efa

uv__udp_finish_close((uv_udp_t*)handle);

That is defined only in the Unix specific implementation ...

I believe this needs to be abstracted.

@nkolban I think the function signature itself is enough to be abstracted. (Because platform specific function signature we name this kind of function as uv_unix_udp_finish_close.) I believe the thing is needed is we implement more functions as we support more platforms.

Howdy ... are you saying that the issue has been accepted as something that will be worked upon? My goal is to port or get running libtuv on the new ESP32 platform and if changes are going to be made in this area, I'll hold off until done.

Ah I assumed that you misunderstood my word the thing is needed is we implement. We don't plan to make a big work on this area. so If you want to extend our platform support, very welcome!

I think we can track this as a duplicate of #49
