# init(forUpdatingAtPath:)

Returns a file handle initialized for reading and writing to the file, device, or named socket at the specified path.

## Declaration

```swift
convenience init?(forUpdatingAtPath path: String)
```

## Parameters

- `path`: The path to the file, device, or named socket to access.

## Return Value

Return Value The initialized file handle object or nil if no file exists at path.

## Discussion

Discussion The file pointer is set to the beginning of the file. The returned object responds to both   read... messages and write(_:). When using this method to create a file handle object, the file handle owns its associated file descriptor and is responsible for closing it.
