# NSRunCriticalAlertPanel

Creates and runs a critical alert panel.

## Declaration

```occ
extern NSInteger NSRunCriticalAlertPanel(NSString *title, NSString *msgFormat, NSString *defaultButton, NSString *alternateButton, NSString *otherButton, ...);
```

## Discussion

Discussion Creates a critical alert panel that warns the user of some critical consequence of a requested action; the panel lets the user cancel the action and may allow the user to modify the action. It then runs the panel in a modal event loop. The panel presented to the user is badged with a caution icon. For more information on using alerts, see Human Interface Guidelines > Alerts. The arguments for this function are the same as those for NSRunAlertPanel.
