Re: Using foreach on a hash passed to a subroutine

in reply to Using foreach on a hash passed to a subroutine

Assuming $config{units}{yourUnit}{interfaces} is a reference to a hash, then \$config{units}{yourUnit}{interfaces} is a reference to a reference to a hash. So you'd have to use ...(keys %{$$h}). I guess you want to drop the backslash.

Thanks all. As pointed out the problem was not in the subroutine but in the nature of the passed parameter. Thanks also for the examples.	[reply]
