win: _get_osfhandle crashes when getting the handle for an fd

[jorangreef]

This is specific to Windows.

It might be more of a libuv issue (see joyent/libuv#1493) but when writing bindings using NAN is there any NAN wrapper that could expose libuv's _get_osfhandle to get the Handle for an fd?

I think the problem for bindings is that the fd is opened by the code compiled as part of Node, but _get_osfhandle can't lookup that fd when called from code compiled as part of a binding.

I think at present there is no way to resolve an fd to a Handle on Windows from a native add-on binding (i.e. any bindings that do fs work can't accept fds on Windows)?

Just to be clear _get_osfhandle is part of the Windows API, but we need a way for bindings to have access to the same _get_osfhandle linked by libuv.

FYI: nodejs/node#6369 & libuv/libuv#1323

Closing, libuv/libuv#1323 happened.
