android - Using polling in jeromq -


i learning use zeromq polling in android . polling on req socket , sub socket in android program(client). client can receive both reply messages server , published messages.

my polling not working. both req socket , publish socket not polled in. if don't use polling both sockets receive message.

i tried searching online not find relevant. client code :

    public void run()    {     zmq.context context = zmq.context(1);     zmq.socket reqsocket = context.socket(zmq.req);     zmq.socket subsocket =context.socket(zmq.sub);     reqsocket.connect("tcp://10.186.3.174:8081");     subsocket.connect("tcp://10.186.3.174:8083");     subsocket.subscribe("".getbytes());     byte[] receivedmessage;     poller poller=context.poller();     poller.register(reqsocket,poller.pollin);     poller.register(subsocket,poller.pollin);      reqsocket.send(msg.getbytes(),0);       while(!thread.currentthread().isinterrupted())      {          if(poller.pollin(0))         {             receivedmessage=s.recv(0);          }           if(poller.pollin(0))           {             receivedmessage=subsocket.recv(0);            }    }     s.close();     context.term();

}

am missing out or doing wrong?

it looks there 3 problems this. main 1 need call poller.poll() first thing inside while loop. why not getting any messages.

the next issue you're checking same index both sockets: expect second if statement needs 

if(poller.pollin(1))

lastly, req socket requires send before every receive, call send needs inside while loop, , before poller.poll() added above :)

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
