# CallbackReturnMode

Used when registering a custom callback using `TSIL.__RegisterCustomCallback()`. Defines how the returned values of the executed functions will be treated and what value is returned by `TSIL.__TriggerCustomCallback()`.

| Enumerator     | Value | Description                                                                                                                                                                                                                                               |
| -------------- | ----- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| NONE           | 0     | Returned values are ignored                                                                                                                                                                                                                               |
| SKIP\_NEXT     | 1     | When a function returns a non nil value the rest are skipped.                                                                                                                                                                                             |
| LAST\_WINS     | 2     | The last function to return a non nil value overwrites all other returned values                                                                                                                                                                          |
| NEXT\_ARGUMENT | 3     | When a function returns a non nil value, the returned value is used as the first argument for the next functions. If a table is returned, the first element of the table will be the first argument, the second element will be the second argument, etc. |
