[dpdk-dev] query about rte_eal_mp_remote_launch()

[Jyotiswarup Raiturkar]

Hi Prashant

Thanks for the reply.

I understand what you said. But my query was can i use pthread_create() to
create the 'tight loop' threads on demand, rather than spawing the threads
at start with rte_eal_mp_remote_launch().  Does anything in the dpdk core
preclude using pthread_create() calls directly?
