# update(repeating:count:)

Update this pointer’s initialized memory with the specified number of consecutive copies of the given value.

## Declaration

```swift
func update(repeating repeatedValue: Pointee, count: Int)
```

## Parameters

- `repeatedValue`: The value used when updating this pointer’s memory.
- `count`: The number of consecutive elements to update. count must not be negative.

## Discussion

Discussion The region of memory starting at this pointer and covering count instances of the pointer’s Pointee type must be initialized or Pointee must be a trivial type. After calling update(repeating:count:), the region is initialized.
