NAME
Hypersonic::Event::Epoll - epoll event backend for Linux
SYNOPSIS
use Hypersonic::Event;
my $backend = Hypersonic::Event->backend('epoll');
# $backend is 'Hypersonic::Event::Epoll'DESCRIPTION
Hypersonic::Event::Epoll is the epoll-based event backend for Hypersonic. It uses edge-triggered mode (EPOLLET) for maximum performance.
epoll is the recommended backend for Linux systems. It provides O(1) event notification for any number of file descriptors.

event_struct
my $struct = Hypersonic::Event::Epoll->event_struct; # 'epoll_event'Returns the C struct name used for the events array.
gen_create($builder, $listen_fd_var)

gen_add($builder, $loop_var, $fd_var)
Generates C code to add a file descriptor to the epoll instance.
gen_del($builder, $loop_var, $fd_var)
Generates C code to remove a file descriptor from the epoll instance.
gen_wait($builder, $loop_var, $events_var, $count_var, $timeout_var)
