# CGDisplayShowCursor(_:)

Decrements the hide cursor count, and shows the mouse cursor if the count is `0`.

```
func CGDisplayShowCursor(_ display: CGDirectDisplayID) -> CGError
```

## Parameters

`display`

This parameter has no effect. By default, you can pass `kCGDirectMainDisplay`.

## Return Value

A result code. To interpret the result code, see [`CGError`](/documentation/CoreGraphics/CGError).

## Discussion

If the hide cursor count is `0`, this function shows the cursor regardless of its current location. The `display` parameter has no effect. In most cases, the caller must be the foreground application to affect the cursor.
