#NAME

IO::Poll - Object interface to system poll call

#SYNOPSIS

use IO::Poll qw(POLLRDNORM POLLWRNORM POLLIN POLLHUP);

$poll = IO::Poll->new();

$poll->mask($input_handle => POLLIN);
$poll->mask($output_handle => POLLOUT);

$poll->poll($timeout);

$ev = $poll->events($input);

#DESCRIPTION

IO::Poll is a simple interface to the system level poll routine.

#METHODS

#mask ( IO [, EVENT_MASK ] )

If EVENT_MASK is given, then, if EVENT_MASK is non-zero, IO is added to the list of file descriptors and the next call to poll will check for any event specified in EVENT_MASK. If EVENT_MASK is zero then IO will be removed from the list of file descriptors.

If EVENT_MASK is not given then the return value will be the current event mask value for IO.
