Here is the new code using use Sys::SigAction. Thanks!!!
use Sys::SigAction qw( set_sig_handler );
....
eval
{
my $code = sub { die "alarm clock restart"; };
my $h = Sys::SigAction::set_sig_handler( 'ALRM', $code, {
+flags => 0, safe => 1 } );
alarm 10; # schedule alarm for every 10 seconds
eval
{
($my_name, $my_aliases, $addrtype, $my_length, @my_add
+r) = gethostbyname($my_hostname);
};
alarm 0;
};
alarm 0;
die if $@ && $@ !~ /alarm clock restart/; #reraise
