# NSIncrementExtraRefCount

Increments the specified object’s reference count.

```
extern void NSIncrementExtraRefCount(id object);
```

## Parameters

`object`

An object.

## Discussion

This function increments the “extra reference” count of `object`. Newly created objects have only one actual reference, so that a single release message results in the object being deallocated. Extra references are those beyond the single original reference and are usually created by sending the object a retain message. Your code should generally not use these functions unless it is overriding the retain or release methods.

### Special Considerations

This function is deprecated and unavailable for use with ARC.
