I have a sub that can fetch the network information of a host. The sub looks like this:

for my $nic (networkInfo()) {
      if (defined $nic->{ip}) {
            print ">>>  IP4 Device: $nic->{device} is using: $nic->{ip
+} address\n" .
        "\tMask: $nic->{mask}\n" .
        "\tBroadcast: $nic->{bcast}\n";
    }
    if (defined $nic->{ip6}) {
        print ">>>  IP6 Device: $nic->{device} is using: $nic->{ip6} a
+ddress\n";
    }
}

The print lines are working, note how the print uses a $nic->{} variable. Okay, so now I want to send 2 variables into a new sub. These two variables are

$platform and $nic->{device}

I have a new sub call that tries to do this but when I get into the subroutine code itself, I don't know how to access the 2nd variable $nic->{device}

Here is the code for my call and the sub so you can see what I am trying to do....

CALL

my @files = getPlatformFiles($platform, $nic->{device});
foreach my $file (@files) {
    print "$file\n";
}

SUB

sub getPlatformFiles {
    my $plat_in = shift;
    my @list;
    if ($plat_in =~ /RedHat/) {
        @list = ("/etc-test/resolv.conf", 
                  "/etc-test/sysconfig/network-scripts/ifcfg-$nic->{de
+vice}");
    }
    return @list;
}

When I run the code I get an message telling me the following: (ignore the line numbers please)

Global symbol "$nic" requires explicit package name at ./new.pl line 1
+85.
Execution of ./new.pl aborted due to compilation errors (#1)
    (F) You've said "use strict vars", which indicates that all variab
+les
    must either be lexically scoped (using "my"), declared beforehand 
+using
    "our", or explicitly qualified to say which package the global var
+iable
    is in (using "::").

Uncaught exception from user code:
        Global symbol "$nic" requires explicit package name at ./new.p

Line 185 is the line in the sub itself with the  $nic->{device} variable
