Use comp to create a component

www.linuxcnc.org/docs/2.5/html/hal/comp.html

component io_connect;
pin io float out;
pin in float in;
function _;
license "GPLv2 or later";
;;
FUNCTION(_) { out = in; }

This is untested...

The license statement will taint the kernel, you need to use only very specific strings there. "GPL" is apparently the one to use.
I think he wanted the "bit" data type. (I don't think I have ever seen a float IO pin, actually)

I guess we need to update the examples in the manual then.
It was copy and pasted and then adapted.
Thought 'tainting' the kernel only produces a whiny message AFAIK.

Yes it was just an example - he didn't specify what he was wanting to do
