    NAME

    IO::Poll - Object interface to system poll call
     
    

    SYNOPSIS

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

        $poll = new IO::Poll;
    
    

        $poll->mask($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"
