I already tried a loop and it didn't work. The bell rings once. In fact my loop was almost identical to yours. Googling around had me find a line like this:
hi everybody,
I just installed Suse on an old Packard Bell.
When the install was at detecting my moden, it hung. I couldn't free it sooooo, I pressed ctrl+alt+backspace.
Yup that killed the process alright.
The machine went right down and upon reboot it is now at the KDE welcome page.

Ok, here's the situation....I have this code...
#include <iostream.h>
#include <stdlib.h>
int main()

cout << "\nBlah, and Blah\n\n";
system("PAUSE");
return 0;
}
Now, "system("PAUSE")" gets executed before "cout" does, and I have... (2 Replies)
Hello
I am trying to tar a whole directory. My problem is that I have to omitt a special subdirectory.
Can you tell my how I am supposed to do that?
Unfortunately I am not very good in regular expressions and in programming. :(
Thanks for any help.
Greetings

This may seem like an odd question, but I've heard that on old Alpha servers running OpenVMS, you could pause the system so that the OS is essentially suspended for a small period of time, then unpause it and it would pick up where it left off. During the pause, all CPU cycles would be halted, all... (3 Replies)
I am running OpenIndiana development version oi_148 32-bit on a seven-year-old Dell Inspiron 8600.
Seems to be running fine except for one particular annoyance: It freezes whenever a system bell/beep plays.
I have mitigated this by turning the system bell off in gnome-terminal, which I use... (3 Replies)

io::async::routine
IO::Async::Routine(3pm) User Contributed Perl Documentation IO::Async::Routine(3pm)NAME
"IO::Async::Routine" - execute code in an independent sub-process
SYNOPSIS
use IO::Async::Routine;
use IO::Async::Channel;
use IO::Async::Loop;
my $loop = IO::Async::Loop->new;
my $nums_ch = IO::Async::Channel->new;
my $ret_ch = IO::Async::Channel->new;
my $routine = IO::Async::Routine->new(
channels_in => [ $nums_ch ],
channels_out => [ $ret_ch ],
code => sub {
my @nums = @{ $nums_ch->recv };
my $ret = 0; $ret += $_ for @nums;
# Can only send references
$ret_ch->send( $ret );
},
on_finish => sub {
say "The routine aborted early - $_[-1]";
$loop->stop;
},
);
$loop->add( $routine );
$nums_ch->send( [ 10, 20, 30 ] );
$ret_ch->recv(
on_recv => sub {
my ( $ch, $totalref ) = @_;
say "The total of 10, 20, 30 is: $$totalref";
$loop->stop;
}
);
$loop->run;
DESCRIPTION
This subclass of IO::Async::Process contains a body of code and executes it in a sub-process, allowing it to act independently of the main
program. Once set up, all communication with the code happens by values passed into or out of the Routine via IO::Async::Channel objects.
Because the code running inside the Routine runs within its own process, it is isolated from the rest of the program, in terms of memory,
CPU time, and other resources, and perhaps most importantly in terms of control flow. The code contained within the Routine is free to make
blocking calls without stalling the rest of the program. This makes it useful for using existing code which has no option not to block
within an "IO::Async"-based program.
To create asynchronous wrappers of functions that return a value based only on their arguments, and do not generally maintain state within
the process it may be more convenient to use an IO::Async::Function instead, which uses an "IO::Async::Routine" to contain the body of the
function and manages the Channels itself.
PARAMETERS
The following named parameters may be passed to "new" or "configure":
channels_in => ARRAY of IO::Async::Channel
ARRAY reference of "IO::Async::Channel" objects to set up for passing values in to the Routine.
channels_out => ARRAY of IO::Async::Channel
ARRAY reference of "IO::Async::Channel" objects to set up for passing values out of the Routine.
code => CODE
CODE reference to the body of the Routine, to execute once the channels are set up.
METHODS
This class provides no additional methods, other than those provided by IO::Async::Process.
