Hi,
dpdk-pdump is secondary process and it must be run along with any primary process.
The primary process must initialize packet capture framework by calling rte_pdump_init() and rt_pdump_uninit() apis, please refer testpmd.c file to see how this is done.
Also I suggest you go through the below docs to understand about the usage. Let me know if you have any questions.
http://dpdk.org/doc/guides/tools/pdump.html ==> dpdk-pdump tool usage is explained
http://dpdk.org/doc/guides/prog_guide/pdump_lib.html ==> Pdump library is explained
Thanks,
Reshma
