# xpc_array_get_data(_:_:_:)

Gets a pointer to the raw bytes of a data object from an array directly.

## Declaration

```swift
func xpc_array_get_data(_ xarray: xpc_object_t, _ index: Int, _ length: UnsafeMutablePointer<Int>?) -> UnsafeRawPointer?
```

## Parameters

- `xarray`: The array which is to be examined.
- `index`: The index of the value to obtain. This value must lie within the index space of the array (0 to N-1 inclusive, where N is the count of the array). If the index is outside that range, the behavior is undefined.
- `length`: Upon return output, will contain the length of the data corresponding to the specified key.

## Return Value

Return Value The underlying bytes at the specified index. NULL if the value at the specified index is not a data value.
