# Prefer to change to rte_event_helper_init() and
introduce the counter part for the same(rte_event_helper_uninit() or rte_event_helper_fini())
# introduce params structure taking another paraments input instead of new APIs.
# let library return rte_event_helper_conf* object for further operations.
