在ACE中如何获得本地的ip地址?

#include "ace/INET_Addr.h"

void print_all_interfaces()
{

ACE_INET_Addr *the_addr_array;
size_t count = 0;

int rc = ACE::get_ip_interfaces (count , the_addr_array);

char address[30];

int i = 0;
while (i < count)
{
  (the_addr_array+i)->addr_to_string(address, sizeof(address));
  printf("%s\n", address);
  i++;
}

delete [] the_addr_array;

system("pause");
}
