# SCDynamicStoreKeyCreateNetworkServiceEntity(_:_:_:_:)

Creates a dynamic store key that can be used to access the per-service network configuration information.

## Declaration

```swift
func SCDynamicStoreKeyCreateNetworkServiceEntity(_ allocator: CFAllocator?, _ domain: CFString, _ serviceID: CFString, _ entity: CFString?) -> CFString
```

## Parameters

- `allocator`: The allocator that should be used to allocate memory for this key. This parameter may be NULL in which case the current default allocator is used. If this value is not a valid doc://com.apple.documentation/documentation/CoreFoundation/CFAllocator, the behavior is undefined.
