Hi, All. Is there any way to process data-types defined in .so library ? I've used code like this :

package SO;

use DynaLoader;

sub new {
    my $class = shift;
    my $libname = shift;
    my $so = DynaLoader::dl_findfile( $libname );
    die 'Failed to find .so for '.$libname unless defined( $so );
    my $lib = DynaLoader::dl_load_file( $so, @_ );
    die 'Failed to load '.$so unless $lib;

    return bless [ $lib, $so ], $class;
};

sub AUTOLOAD {
    my $self = shift;
    my $sub = $AUTOLOAD;
    $sub =~ s/.*\:\://;

    warn 'called DL';
    return $self->call( $sub, @_ );
};

sub DESTROY {
    my $self = shift;
    DynaLoader::dl_unload_file( $self->[0] );
};

sub call {
    my $self = shift;
    my $sym = shift;
    my $symref = DynaLoader::dl_find_symbol( $self->[0], $sym );
    die 'failed to find '.$sym.' in '.$self->[1] unless $symref;

    DynaLoader::dl_install_xsub( $sym, $symref );
    return &$sym( @_ );
};

------ I've tried to install C::DynaLib but get failed on tests in "make test". At now I'm looks over code of C::DynaLib and many others. Showed ecample works good with method which is like that

use SO;
my $so = SO->new('some.so');
my $string = $so->get_some_string();#correct result
my $x = { a => 'b', c => 123 };
my $r = $so->change_this_argument( $x );#get error from .so about wron
+g arguments, but the arguments definetly correct.
my $r2 = $so->accept_this_argument( $x );#get same error.

My question is how I should to repack $x or it's components to make them clear for original .so library. .so library is third party library which sources I have but will not like to change ( it comes from yum official repositories ).
