Hi friend, after some hours of works I think I've finally understood the problem, in few words in the source code 
our @AS = qw(
   driver
   interface
   _drv
   _context
);

__PACKAGE__->cgBuildAccessorsScalar(\@AS);
__PACKAGE__->cgBuildIndices;

sub new {
   my $self = shift->SUPER::new(
      driver    => "madwifing",
      interface => "wlo1",
      @_,
   );

the @_ (under the "new" ) assign a value to $self->_drv and $self->_context, this explain the "undef" obtained in the previous posts, the output of this small program confirm it: 
udo perl -e '
use Net::Lorcon2 qw( :subs );
my $lorcon = Net::Lorcon2->new();
use Data::Dumper; 
print Dumper($lorcon);
'

[download]
outputs 
$VAR1 = bless( [
                 'madwifing',
                 'wlo1',
                 \152948280,
                 \152839568
               ], 'Net::Lorcon2' );

including the $lorcon variable into the  Net::Lorcon2::lorcon_open_inject( $lorcon ) still crash but I think that the problem now stands in the BLESS reference, some hints? Regards Edoardo M
