Handles and kernel objects in zxdb
List all handles and VMOs (some of these "Virtual
Memory Objects" can be mapped but won't have open handles) with the handles command.
```none {:.devsite-disable-click-to-copy}
[zxdb] handles
Handle Type Koid
Or you can look up an object by koid. Koid lookup will only search the objects in the debugged process and won't match arbitrary kernel objects owned by other processes. Koid lookup is the only way to show detailed information for mapped VMOs that have no open handles.
