# TECSnifferObjectRef

Defines a reference to an opaque sniffer object.

## Declaration

```occ
typedef struct OpaqueTECSnifferObjectRef *TECSnifferObjectRef;
```

## Discussion

Discussion When analyzing text for possible encodings, the Text Encoding Converter requires a reference to a sniffer object that specifies what types of encodings can be detected. You receive this reference when calling the function TECCreateSniffer. A sniffer object reference is defined by the TECSnifferObjectRef data type. The structure of the OpaqueTECObjectRef data type is private, and a sniffer object is not accessible directly.
