Re: [zeromq-dev] CZMQ: zloop_poller terminates the function handler
Hello, Please ignore my previous message. That was due to a bug in the design and has nothing to do with the CZMQ library.

Re: [zeromq-dev] CZMQ: zloop_poller terminates the function handler
Hello, I think I fixed the issue. It was due to invoking zstr_free inside the handler without passing the address of the pointer. zstr_free(msg) --> Lead to termination of poller zstr_free(&msg) --> Fixed the issue .i.e. event handler is not being terminated anymore. I guess any error inside the handler leads to poller termination as per CZMQ implementation. Nevertheless, I have another query regarding timers. Timer expired for 400 Timer expired for 200 Timer expired for 100 Timer expired for 300 Timer expired for 400 Numbers that you see above are some object IDs. Each timer for each object ID expires after a time interval of 15000 ms. As per the scenario that I am trying to design when the poller socket has an event (some message), I cancel the timer of these objects. I see that the timer cancellation with zloop_timer_end --> leads to handler termination. Below is the code snippet. [image: Inline image 1] I see my program exits when I cancel some timers upon receving the message on the poller socket. Is it that I should wait until a particular timer_id expires and its handle is triggered so that the timer could be cancelled from within the handler? Please suggest. thanks & regards, Shrikanth On Tue, Jan 17, 2017 at 11:42 AM, Luca Boccassi wrote: > On Tue, 2017-01-17 at 00:42 +0100, Shrikanth M.D. wrote: > > Hello All, > > > > I have a zloop_poller invoked as below: > > zloop_poller (loop, &item, s_netconf_socket_event,inter_thread_pair); > > > > > > I see that while executing the function handles, s_netconf_socket_event, > my > > program terminates. > > I have added debugs and see no obvious issues with my program. > > > > Is there any explicit cause due to which czmq would end the handler by > > itself? > > > > Regards, > > Shrikanth > > Can you provide a code snippet that reproduces the case? > > ___ > zeromq-dev mailing list > zeromq-dev@lists.zeromq.org > https://lists.zeromq.org/mailman/listinfo/zeromq-dev > ___ zeromq-dev mailing list zeromq-dev@lists.zeromq.org https://lists.zeromq.org/mailman/listinfo/zeromq-dev

[zeromq-dev] CZMQ: zloop_poller terminates the function handler
Hello All, I have a zloop_poller invoked as below: zloop_poller (loop, &item, s_netconf_socket_event,inter_thread_pair); I see that while executing the function handles, s_netconf_socket_event, my program terminates. I have added debugs and see no obvious issues with my program. Is there any explicit cause due to which czmq would end the handler by itself?
