# nw_framer_parse_input(_:_:_:_:_:)

Examines the content of input data while inside your input handler block.

## Declaration

```swift
func nw_framer_parse_input(_ framer: nw_framer_t, _ minimum_incomplete_length: Int, _ maximum_length: Int, _ temp_buffer: UnsafeMutablePointer<UInt8>?, _ parse: (UnsafeMutablePointer<UInt8>?, Int, Bool) -> Int) -> Bool
```

## Parameters

- `framer`: A network framer instance.
- `minimum_incomplete_length`: The minimum number of bytes that should be delivered to the parse completion.
- `maximum_length`: The maximum number of bytes that should be delivered to the parse completion.
- `temp_buffer`: An optional buffer into which the parser will copy bytes. Use this if you need to make guarantees about byte alignment.
- `parse`: A completion handler that will be called inline to examine a region of bytes.

## Return Value

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