Return Values
| Value | Description |
|---|---|
| S_OK | Function completed successfully. |
| FAILED(hr) | Appropriate error message. |
Remarks
By default, the engine returns zero recognition alternates, so an application must call ::SetMaxAlternates to retrieve alternates. The value of cAlternates is the maximum number of recognition alternates that will be returned to the application.
