# os_trace_type_enabled(_:)

Returns whether the specified info level trace information is enabled.

## Declaration

```swift
func os_trace_type_enabled(_ type: UInt8) -> Bool
```

## Parameters

- `type`: The type of trace to check. Possible values are doc://com.apple.os/documentation/os/OS_TRACE_TYPE_DEBUG and doc://com.apple.os/documentation/os/OS_TRACE_TYPE_INFO.

## Discussion

Discussion Generally, trace points should not involve expensive operations, however some circumstances warrant it. Use this function to do expensive work only when a given level of trace messages are enabled.
