Hi! I am using ROUTER/DEALER pattern.Here is the use case:I wanna control
specific client(DEALER) through sending specific message from
server(ROUTER).Here is the client side:
void *context = zmq_ctx_new ();
void *client = zmq_socket (context, ZMQ_DEALER);
zmq_setsockopt (client, ZMQ_IDENTITY, "client", 6);
zmq_connect (client, "tcp://localhost:5671");
while (1)
{
char *instruction = s_recv (client);
if(strcmp(instruction,"kill")==0)
return 0;
zmq_close (client);
zmq_ctx_destroy (context);
return 0;
}
Here is the server side:
void *context = zmq_ctx_new ();
void *server = zmq_socket (context, ZMQ_ROUTER);
zmq_bind (server, "tcp://*:5671");
while (1)
{
char clientname[128];
char instruction[128];
printf("client name\n");
scanf("%s",clientname);
printf("instruction\n");
scanf("%s",instruction);
s_sendmore(server,clientname);
s_send(server,instruction);
}
zmq_close (server);
zmq_ctx_destroy (context);
return 0;
For the first time,I can control client through sending
message:clientname=client;instruction=kill
But when the client exits and I restart it, I can not send any messages to
client.The ID of client did not change .But why can not i send message to it
after restarting it???_______________________________________________
