Terminating re_main function

[simon-eis]

Hi,

i am using baresip and the libre in a custom c++-application. The re_main function is blocking and called in a separate thread. At defined user input the re_main loop stops and the execution is finished. Although i am not completly sure if i am breaking the re_main loop correctly. I am using a timer with a cyclical timeout of 1 second and also emit the signal SIGALRM with the following signal handler.

    void signalHandler(int sig)
    {
        ua_stop_all(true);
        re_cancel();
    }

If i am just using the signal handler without the timer the re_main loop needs sometimes more than 30 seconds to break. I am using the poll method where the fd_poll() function blocks.
Am i breaking the re_main loop correctly or is there another more convenient method to break the loop?
Why is it taking sometimes so long until the loop is exited?

Thanks in advance.
