# SCDynamicStoreCreate(_:_:_:_:)

Creates a new session used to interact with the dynamic store maintained by the System Configuration server.

```
func SCDynamicStoreCreate(_ allocator: CFAllocator?, _ name: CFString, _ callout: SCDynamicStoreCallBack?, _ context: UnsafeMutablePointer<SCDynamicStoreContext>?) -> SCDynamicStore?
```

## Parameters

`allocator`

The allocator that should be used to allocate memory for the local dynamic store object. 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.

`name`

The name of the calling process or plug-in of the caller.

`callout`

The function to be called when a watched value in the dynamic store is changed. Pass `NULL` if no callouts are desired.

`context`

The context associated with the callout. See [`SCDynamicStoreContext`](/documentation/SystemConfiguration/SCDynamicStoreContext) for more information about this value.

## Return Value

A reference to the new dynamic store session. You must release the returned value.
