this should be included after libudev.h since it's a C++ include.

[marcheu, 2011/04/14 20:41:24]

Done.

Thinking about this now, I'd rename this to UdevDelegate.

[marcheu, 2011/04/14 20:41:24]

Done.

And maybe this to UdevController? I know it's listener because of EventHandler,
but on chromium we tend to use Listener for interfaces.

[marcheu, 2011/04/14 20:41:24]

Done.
