 To do so you can use the second parameter passed in all functions provided to the taskMap `toggleIPC` which is prototyped as follow :
 
 `toggleIPC(messageBroker: function, initalize: function): Promise`
-- `messageBroker` is prototyped as `messageBroker(msg: Any, closeIPC: function)`
+- `messageBroker` is prototyped as `messageBroker(msg: Any)`
 - `initialize` is prototyped as `initialize(sendMessageToMaster: function)`<br/>
 
 because `toggleIPC` returns a promise you must return it (recursively), otherwise the job will be considered done, and the worker Idle.<br/>
