Paul, Could you please add one more output parameter "bool *mem_range_contiguous" to this function, returning true if the memory chunks are contiguous. It will be useful instead of implementing get_memhdr_info() locally in this other patch series: https://inbox.dpdk.org/dev/mw4pr11mb58724ac82a34a3eefef78e898e...@mw4pr11mb5872.namprd11.prod.outlook.com/ Please coordinate this change directly with Frank Du <frank...@intel.com>. -Morten
