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 

 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

Reference 1: Code to launch function in main program. 

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