# OSLogInt32ExtendedFormat.darwinSignal

A format that displays a 32-bit integer as a Darwin signal.

## Declaration

```swift
case darwinSignal
```

## Discussion

Discussion Use this option to format the interpolated value as a Darwin signal, such as sigsegv: Segmentation fault. The following example applies the darwinSignal formatter to the 32-bit integer value 25: // Create a logger with the specified subsystem and category. let logger = Logger(subsystem: "com.example.OSLogValueFormatting",                     category: "Formatter Output")                  // Assign the value to interpolate. let value: Int32 = 25                  // Write the value to the log using the specified format. logger.info(".darwinSignal output is \(value, format: .darwinSignal)") And the system writes the following message to the log: [Formatter Output] .darwinSignal output is [sigxfsz: Filesize limit exceeded]
