# TECClearSnifferContextInfo

Resets a sniffer object to its initial settings so youcan reuse it.

## Declaration

```occ
OSStatus TECClearSnifferContextInfo(TECSnifferObjectRef encodingSniffer);
```

## Parameters

- `encodingSniffer`: A pointer to the sniffer object you want to reset.

## Return Value

Return Value A resultcode. See Result Codes.

## Discussion

Discussion Sniffers maintain state information about the input encodingbuffer and the number of errors and features found for each encoding;this information allows a caller to progressively sniff an inputbuffer in sequential chunks. Before sniffing a buffer that containscompletely new information you must clear any state informationby calling TECClearSnifferContextInfo.
