## NAME

rte\_memseg\_list

## SYNOPSIS

`#include <rte_memory.h>`

### Data Fields

uint64\_t **page\_sz**\
 int **socket\_id**\
 volatile uint32\_t **version**\
 size\_t **len**\
 unsigned int **external**\
 unsigned int **heap**\

## Detailed Description

memseg list is a special case as we need to store a bunch of other data together with the array itself.
