File not found `sys/ioctl.h` on Windows

[Michael-F-Bryan]

In wasmerio/wasmer's CI, we've seen some build failures on Windows (link) where the build script is trying to access a header file that doesn't exist.

We're using interfaces v0.0.9 with default features.

error: failed to run custom build command for `interfaces v0.0.9`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_RELEASE_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.

Caused by:

Same problem.

[Llorx]

Same problem. Bump.

Same problem

Currently Windows is not supported. I added README about it.

[Llorx]

Soooo only unix-alike systems. Weird "cross-platform manner" you have there xD

[dalance]

I'm not the original author, but I guess that the author intended that "cross-platform" means Linux, *BSD, macOS, Android, and so on. So I don't think that the expression is inappropriate.

Of course, if anyone contribute to add Windows support, I'll merge it.

[Tnze]

Agree

[JoshLambda]

As a workaround, it's possible to replace this crate with the crate get_if_addrs which supports Windows, Linux, and macOS.
