in thread Help with Lorcon XS library

some functions ( like the lorcon_list_drivers ) works properly

I don't know much about Net::Lorcon2, but I'm guessing that the string that you assign to $driver must be the same as one of the strings listed by lorcon_list_drivers().
What happens if you assign those strings (as shown by Dumper(\@cards)) to $driver ?
Could you provide us with the output of Dumper(\@cards) from that second program I posted.

Cheers,
Rob

    If this is the lorcon in question:

    Current State:
The lorcon2 rewrite currently only supports the mac80211 driver,
additional drivers will be restored over time

    Hi the output of the 
     lorcon_lsit_driver is:
$VAR1 = [
          {
            'name' => 'rtfile',
            'details' => 'Real-time PCAP file source'
          },
          {
            'details' => 'PCAP file source',
            'name' => 'file'
          },
          {
            'name' => 'madwifing',
            'details' => 'Linux madwifi-ng drivers, deprecated by ath5
+k and ath9k'
          },
          {
            'name' => 'tuntap',
            'details' => 'Linux tuntap virtual interface drivers'
          }
        ];

    I have already tried if I use: 
     
  print Net::Lorcon2::lorcon_create("wlo1", $driver); #where $driver c
+an be madwifing or other it says:
  
  Net::Lorcon2::lorcon_create: driver is not a reference at -e line 3.

    [download]
    and if I do 
       print Net::Lorcon2::lorcon_create("wlo1", \$driver); #where $driver
+ can be madwifing or other it says
   segmentation error (core dump created)

      Yes - you should not do that.
      As the error message says $driver is not a reference. 

         print Net::Lorcon2::lorcon_create("wlo1", \$driver); #where $driver
+ can be madwifing or other it says
   segmentation error (core dump created)

      Yes - you should not do that either. At least, this time you have passed something that is a reference.
      But it's not a reference to the right thing, and therefore causes a segfault.

      As I said in my first post, the correct thing to do would be: 
      my $driver = "madwifing";
my $if = "wlo1";

my $drv = lorcon_find_driver($driver);
if (! $drv) {
   print STDERR "[-] Unable to find DRV for [$driver]\n";
   exit 1;
}

my $lorcon = lorcon_create($if, $drv);
if (! $lorcon) {
  print STDERR "[-] lorcon_create failed\n";
  exit 1;
}

      What happens if you do that ?
      In view of what marto dug up, it may not work either - but it's at least worth a try.

      Cheers,

        Hi! Many thanks, now it works, It is pretty strange but I think that the problem was related to the string passed as $driver and not to the XS code, WOW i am so happy, would you like to be thanked in the page of metacpan? under the voice HERO of the module. still many thanks, Regards Edoardo M
