  Target Milestone: ---

We have written application where EAL initialization and resource allocation
done in main program. Then we are launching/calling a function below
code(Reference 1).Launched Function is responsible for creating thread and
perform corresponding job,but we see that after thread completes it's job we
are not able to exit from application it gets hanged. 
And we are seeing newly created thread unable to access lcore value as accessed
by main thread.
using below function 
rte_lcore_id()

 Below is command used to run application.

#./<executable file> -l 1-2 -d /usr/local/lib/librte_pmd_e1000.so.1.1 -w
0000:04:00.1 -w 0000:04:00.2

Also whatever statement/code written after below code is not executed in main
thread.

Reference 1: Code to launch function in main program. 
________________________________________

rte_eal_mp_remote_launch(<function_name>,NULL, CALL_MASTER);
RTE_LCORE_FOREACH_SLAVE(lcore) {
      if(rte_eal_wait_lcore(lcore) < 0 ) {
                     return -1;
                   }
 }


can you please guide us what is the correct procedure to run DPDK application
as separate thread/Tell us what is the mistake we are doing?.

Thanks & Regards,
ullas
