Dear Monks,

I'm using IO::Select in order to switch between different clients connected to the same server program. At first, I used a sample code to understand how IO::Select works. That code uses the select() method in order to find the clients that have produced some output, like this: 

$read_set = new IO::Select(); # create handle set for reading
$read_set->add($socket);      # add the main socket to the set
# Get a set of readable handles (blocks until at least one handle is r
+eady)
my ($rh_set) = IO::Select->select($read_set, undef, undef, 0);

Now, after reading the module's documentation, I'm trying to understand what's the difference between using can_read() and select(). Can the last line in the above extract be written as  my @rh_set = $read_set->can_read(); ?

I can see that one method is static whole the other is not, and that one returns references to arrays, while the second returns one array - but are there any differences in the results themselves? Is one of them somehow "better" to use than the other?

Thanks a lot!
