## ifUserData

### SetUserData(user\_data As Object)

Sets the user data that will be returned when events are raised.

### GetUserData() As Object

Returns the user data that has previously been set via `SetUserData()`. It will return Invalid if no data has been set

## ifDiskErrorEvent

### GetDiskError() As Object

Returns an *roAssociativeArray* containing the following parameters:

| **Key** | **Type**     | **Description**                                                             |
| ------- | ------------ | --------------------------------------------------------------------------- |
| source  | *roString*   | The error type                                                              |
| time    | *roDateTime* | The time at which the error occurred (with millisecond accuracy)            |
| device  | *roString*   | The internal name for the device generating the error                       |
| error   | *roString*   | A description of the error (e.g."Timeout")                                  |
| param   | *roString*   | The error parameter (use depends on type of error (e.g. the sector number)) |

Example:

```text
aa = msgp.GetDiskError()
report = "Time: " + aa["Time"] + "Error: " + aa["source"] + " " + aa["error"] + " " + aa["device"] + " " + aa["param"]
```

:::hint{type="info"}
This example uses an implicit conversion of *roDateTime*. You could also use *roDateTime.GetString()*.
