# parseInput(minimumIncompleteLength:maximumLength:parse:)

Examines the content of input data while in your input handler.

## Declaration

```swift
final func parseInput(minimumIncompleteLength: Int, maximumLength: Int, parse: (UnsafeMutableRawBufferPointer?, Bool) -> Int) -> Bool
```

## Parameters

- `minimumIncompleteLength`: The minimum number of bytes that should be delivered to the parse completion.
- `maximumLength`: The maximum number of bytes that should be delivered to the parse completion.
- `parse`: A completion handler that will be called inline to examine a region of bytes. This will contain the buffer that matches the constraints, and a boolean indicating if this buffer represents the end of a message.

## Return Value

Return Value Returns true if the requested length was available to parse, or false if the conditions could not be met.
