Hi I have a program that captures packets with the libpcap library by calling the pcap-functions, e.g. pcap_next(...).
I would like to use PF_RING for the program and therefore I would have to adjust the calling functions to
pfring_open(...)

Alzabo::ChangeTracker(3pm) User Contributed Perl Documentation Alzabo::ChangeTracker(3pm)NAME
Alzabo::ChangeTracker - Saves a set of changes as callbacks that can be backed out if needed
SYNOPSIS
use Alzabo::ChangeTracker;
my $x = 0;
my $y = 1;
sub foo
{
my $tracker = Alzabo::ChangeTracker->new;
$tracker->add( sub { $x = 0; } );
$x = 1;
bar();
eval { something; };
$tracker->backout if $@;
}
sub bar
{
my $tracker = Alzabo::ChangeTracker->new;
$tracker->add( sub { $y = 1; } );
$y = 2;
}
DESCRIPTION
The trick ...
We only want to have one object of this type at any one time. In addition, only the stack frame that created it should be able to clear it
(except through a backout). Why? Here's an example in pseudo-code to help explain it:
sub foo
{
create a tracker;
store some change info in the tracker;
call sub bar;
store some change info in the tracker;
# point Y
clear changes in tracker;
}
sub bar
{
create a tracker; # internally, we really just increment our stack count
store some change info in the tracker;
clear changes in tracker; # point X
}
If at point X we were to really clear out the changes, even the changes just from sub bar, we'd have a problem. Because if at point Y,
things go to hell and we want to back out the changes, we want to back out the changes from sub foo _AND_ sub bar. However, if bar is also
an entry point we want to be able to track changes in bar and clear them from bar.
