# NSWindowList

Gets information about onscreen windows.

## Declaration

```occ
extern void NSWindowList(NSInteger size, NSInteger list[]);
```

## Discussion

Discussion Provides an ordered list of all onscreen windows. It fills list with up to size window numbers; the order of windows in the array is the same as their order in the window server’s screen list (their front-to-back order on the screen). Use the count obtained by NSCountWindows to specify the size of the array for this function.
