I was trying to read the STDIN without stop the script in this point. To do that I have 2 options, use IO::Select or alarm(). But this doesn't work for Win32!!! I'm using Perl 5.8.0 (alarm() is only enabled on it for Win32) on Win2K.

Here are the tests:

Test IO::Select: 

  use IO::Select ;
  
  my $timeout = 5 ;
  my $stdin = \*STDIN ;

  my $ios = IO::Select->new( $stdin ) ;

  for(;;) {
    my $sel = $ios->can_read($timeout) ;
    my $buffer ;
    print "Reading ($timeout\s)...\n" ;
    1 while( read( \*STDIN , $buffer, 1 , length($buffer) ) ) ;
    print "Read:<$buffer>" ;
  }

Test Alarm: 
  my $timeout = 5 ;
  for(;;) {
    eval {
      local $SIG{ALRM} = sub { die "DIE_ALARM\n" } ;
      alarm $timeout ;
      my $buffer;
      print "Reading ($timeout\s)...\n" ;
      1 while( read( \*STDIN , $buffer, 1 , length($buffer) ) ) ;
      print "Read:<$buffer>" ;
      alarm 0 ;
   };
   if ($@ !~ /DIE_ALARM/s) { die $@ }
 }
