if ; then
rm -f $file
exit 0

io::poll
IO::Poll(3pm) Perl Programmers Reference Guide IO::Poll(3pm)
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"
