IO::Poll - phpMan

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.

    poll ( [ TIMEOUT ] )
        Call the system level poll routine. If TIMEOUT is not specified then
        the call will block. Returns the number of handles which had events
        happen, or -1 on error.

    events ( IO )
        Returns the event mask which represents the events that happened on
        IO during the last call to "poll".

    remove ( IO )
        Remove IO from the list of file descriptors for the next poll.

    handles( [ EVENT_MASK ] )
        Returns a list of handles. If EVENT_MASK is not given then a list of
        all handles known will be returned. If EVENT_MASK is given then a
        list of handles will be returned which had one of the events
        specified by EVENT_MASK happen during the last call ti "poll"
