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" SEE ALSO
