But once more, if i want pass 2 or more hashes to subroutine, is it the same?
It was already in my answer, (although I minimally updated it silently for added clarity). Minimal example using a prototype: 
#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

sub foo (\%\%) {
    Dumper @_;
}

my %a=(foo => 1, bar =>2);
my %b=(%a, bax => 3);
print foo %a, %b;

__END__
