# ConstUnicodeMappingPtr

Defines a constant Unicode mapping pointer.

## Declaration

```occ
typedef const UnicodeMapping *ConstUnicodeMappingPtr;
```

## Discussion

Discussion Many Unicode Converter functions take a pointer to a Unicode mapping structure as a parameter. For functions that do not modify the Unicode mapping contents, the Unicode Converter provides a constant pointer to a Unicode mapping structure defined by the ConstUnicodeMappingPtr data type.
