class var standardInput: FileHandle { get }
```

## Return Value

## Discussion

Discussion Conventionally this is a terminal device on which the user enters a stream of data. There’s one standard input file handle per process; it’s a shared instance. When using this method to create a file handle object, the file handle owns its associated file descriptor and is responsible for closing it.
