# SCNetworkSetAddService(_:_:)

Adds the specified network service to the specified set.

## Declaration

```swift
func SCNetworkSetAddService(_ set: SCNetworkSet, _ service: SCNetworkService) -> Bool
```

## Parameters

- `set`: The set (the complete configuration for a single location).
- `service`: The service to add to the set.

## Return Value

Return Value TRUE if the service was added to the set; FALSE if the service was already present or an error occurred.

## Discussion

Discussion Prior to OS X v10.5, the Network Preferences pane did not support having a single service being a member of more than one set. Therefore, an error is returned if you attempt to add a service to more than one set on a pre-10.5 system.
