There’s no such thing yet, right? “?” is a good enough description. This is not
a good place for speculation, because nobody will update it in the future and it
will become stale and confusing.

Done.

Same.

What does iProd mean?

What’s it return on a simulator? Just the Mac model name?

This doesn’t explain why this function needs an argument at all or what the
argument should look like or do.

[Chen Yu, 2012/07/27 16:28:17]

Done.

+std::string GetMacAddress(std::string ifName);

[Mark Mentovai, 2012/07/25 14:00:23]

ifName should not use camelCase. Also, don’t abbreviate. interface_name.

[Mark Mentovai, 2012/07/25 14:00:23]

The argument type should be const std::string&. No need to give the function its
own copy of the string.
