VERSION

version 0.002

SYNOPSIS

use IO::Async::Loop;
use Net::Async::ZMQ;
use Net::Async::ZMQ::Socket;

use ZMQ::LibZMQ3;  # or ZMQ::LibZMQ4
use ZMQ::Constants qw(
  ZMQ_REQ
  ZMQ_NOBLOCK
  ZMQ_EVENTS ZMQ_POLLIN
);

my $loop = IO::Async::Loop->new;

my $ctx = zmq_init();
my $client_socket = zmq_socket( $ctx, ZMQ_REQ );
zmq_connect( $client_socket, "tcp://127.0.0.1:9999" );

my $counter = 0;

my $zmq = Net::Async::ZMQ->new;

zmq_sendmsg( $client_socket, "initial message" );

$zmq->add_child(
  Net::Async::ZMQ::Socket->new(
    socket => $client_socket,
    on_read_ready => sub {
      while ( zmq_getsockopt( $client_socket, ZMQ_EVENTS ) & ZMQ_POLLIN ) {
        my $recvmsg = zmq_recvmsg( $client_socket, ZMQ_NOBLOCK );
        my $msg = zmq_msg_data($recvmsg);
        zmq_sendmsg( $client_socket, "hello @{[ $counter++ ]}" );
      }
    },
  )

$loop->add( $zmq );

$loop->run;
