# DISPATCH_IO_STRICT_INTERVAL

Enqueue handlers for a channel at strict intervals regardless of how much data has been read or written.

## Declaration

```swift
var DISPATCH_IO_STRICT_INTERVAL: Int32 { get }
```

## Discussion

Discussion Setting this flag can lead to the handler being called even if the amount of data does not exceed the channel’s low-water mark.
