# string(withCString:length:)

Returns a string containing the characters in a given C-string.

## Declaration

```swift
class func string(withCString bytes: UnsafePointer<CChar>, length: Int) -> Any?
```

## Discussion

Discussion cString must not be NULL. cString should contain characters in the default C-string encoding. This method converts length * sizeof(char) bytes from cString and doesn’t stop short at a NULL character.
