# dispatch_workloop_create_inactive Creates a new inactive workloop with the specified label. ``` extern dispatch_workloop_tdispatch_workloop_create_inactive(const char *label); ``` ## Parameters `label` A string label to attach to the queue to uniquely identify it in debugging tools such as Instruments, `sample`, stackshots, and crash reports. Because apps, libraries, and frameworks can all create their own dispatch queues, a reverse-DNS naming style (`com.example.myqueue`) is recommended. This parameter is optional and can be `NULL`. ## Return Value The newly created workloop. ## Discussion Use this function when you want to change the default behavior of the workloop before activating it. For example, use this method if you call [`dispatch_set_qos_class_floor`](/documentation/Dispatch/dispatch_set_qos_class_floor) to configure the minimum quality of service level. After configuring the workloop, you must call [`activate()`](/documentation/Dispatch/DispatchObject/activate()) before submitting any blocks to it. If you submit blocks to an inactive workloop, the system terminates the current process. --- Copyright © 2026 Apple Inc.
