| $poll = IO::Poll->new Creates a new IO::Poll object. Unlike IO::Select, new() does not accept arguments. $mask = $poll->mask($handle [$mask]) Gets or sets the current event bitmask for the indicated handle. If no mask argument is specified, the current one is returned. Otherwise, the argument is used to set the mask. A mask of removes the handle from the monitored set entirely. All handles are monitored for error conditions ( POLLNVAL, POLLERR, POLLHUP ) whether you request it in the bitmask or not. $poll->remove($handle) Removes the handle from the polling list. This is exactly equivalent to calling mask() with a bitmask argument of . $events = $poll->poll([$timeout]) Wait until a monitored handle has an event or until $timeout occurs, returning the number of handles with events. $timeout is given in seconds and may be fractional . A timeout of results in nonblocking behavior. An absent timeout, or a timeout of -1, causes poll() to block indefinitely. @handles = $poll->handles([$mask]) Called with no arguments, handles() returns a list of all handles known to the IO::Poll object. Called with a bitmask of events, it returns all handles that had one of the specified events during the previous call to poll() . $mask = $poll->events($handle) The events() method returns a bitmask containing all the events involving $handle that occurred during the previous call to poll() . |
