Functions

25       epoll support
26
27       $ok = epoll_defined()
28           Returns true if epoll might be available.  (caller must still test
29           with epoll_create)
30
31       $epfd = epoll_create([ $start_size ])
32           Create a new epoll filedescriptor.  Returns -1 if epoll isn't
33           available.
34
35       $rv = epoll_ctl($epfd, $op, $fd, $events)
36           See manpage for epoll_ctl
37
38       $count = epoll_wait($epfd, $max_events, $timeout, $arrayref)
39           See manpage for epoll_wait.  $arrayref is an arrayref to be modi‐
40           fied with the items returned.  The values put into $arrayref are
41           arrayrefs of [$fd, $state].
42
43       sendfile support
44
45       $ok = sendfile_defined()
46           Returns true if sendfile should work on this operating system.
47
48       $sent = sendfile($sock_fd, $file_fd, $max_send)
49           Sends up to $max_send bytes from $file_fd to $sock_fd.  Returns
50           bytes actually sent, or -1 on error.
