Writing The 'access_data_at' Macro

• And now the macro that prints the Nth element in the list:

  define access_data_at
          if $argc == 1
                  set $access_data_index = 0
                  set $ad_curr = g_access_list_head
                  while $access_data_index < $arg0
                          if $ad_curr == 0
                                  loop_break
                          else
                                  set $ad_curr = $ad_curr->next
                          end
                          set $access_data_index = $access_data_index + 1
                  end
                  if $ad_curr != 0
                          print *(struct access_data*)$ad_curr->data
                  end
          else
                  print "missing index"
          end
  end
