# updateAVCCommandTimeout

By default, AVCCommands timeout 10 seconds after receiving an Interim response. This function resets the timeout of the current command to 10 seconds from the current time. Call this repeatedly for AVC commands that take a very long time to execute to prevent premature timeout.

## Declaration

```occ
virtual IOReturn updateAVCCommandTimeout(); 
```
