    Hello Adam,
    If you are looking for code to protect some region of application flow from context/Task switching, then in the application itself you need to disable interrupt around the critical section to avoid any switching.
    /* Critical Section: We record the spawn function which is to be executed */
    key = Hwi_disable();
    ....
    /* Critical section that needs to be protected from Task switch */
    Hwi_restore (key);
