io::async::loop::epoll
IO::Async::Loop::Epoll(3pm) User Contributed Perl Documentation IO::Async::Loop::Epoll(3pm)NAME
IO::Async::Loop::Epoll - use "IO::Async" with "epoll" on Linux
SYNOPSIS
use IO::Async::Loop::Epoll;
use IO::Async::Stream;
use IO::Async::Signal;
my $loop = IO::Async::Loop::Epoll->new();
$loop->add( IO::Async::Stream->new(
read_handle => *STDIN,
on_read => sub {
my ( $self, $buffref ) = @_;
while( $$buffref =~ s/^(.*)
?
// ) {
print "You said: $1
";
}
},
) );
$loop->add( IO::Async::Signal->new(
name => 'INT',
on_receipt => sub {
print "SIGINT, will now quit
";
$loop->loop_stop;
},
) );
$loop->loop_forever();
DESCRIPTION
This subclass of IO::Async::Loop uses IO::Epoll to perform read-ready and write-ready tests so that the O(1) high-performance multiplexing
of Linux's epoll_pwait(2) syscall can be used.
The "epoll" Linux subsystem uses a registration system similar to the higher level IO::Poll object wrapper, meaning that better performance
can be achieved in programs using a large number of filehandles. Each epoll_pwait(2) syscall only has an overhead proportional to the
number of ready filehandles, rather than the total number being watched. For more detail, see the epoll(7) manpage.
This class uses the epoll_pwait(2) system call, which atomically switches the process's signal mask, performs a wait exactly as
epoll_wait(2) would, then switches it back. This allows a process to block the signals it cares about, but switch in an empty signal mask
during the poll, allowing it to handle file IO and signals concurrently.
CONSTRUCTOR
$loop = IO::Async::Loop::Epoll->new()
This function returns a new instance of a "IO::Async::Loop::Epoll" object.
METHODS
As this is a subclass of IO::Async::Loop, all of its methods are inherited. Expect where noted below, all of the class's methods behave
identically to "IO::Async::Loop".
$count = $loop->loop_once( $timeout )
This method calls the "poll()" method on the stored "IO::Epoll" object, passing in the value of $timeout, and processes the results of that
call. It returns the total number of "IO::Async::Notifier" callbacks invoked, or "undef" if the underlying "epoll_pwait()" method returned
an error. If the "epoll_pwait()" was interrupted by a signal, then 0 is returned instead.
