| * Completion Routine |
| * |
| * NFC-FRI components that work in an overlapped style need to provide a |
| * function that is compatible to this definition. It is mandatory to define |
| * such a routine for components that interact with other components up or down |
| * the stack. Moreover, such components shall provide a function within their |
| * API to enable the setting of the Completion Routine address and parameters. |
| * |
| * First Parameter: Context |
| * Set to the address of the called instance (component instance context |
| * structure). For instance, a component that needs to give control to a |
| * component up the stack needs to call the completion routine of the upper |
| * component. The value to assign to this parameter is the address of the |
| * context structure instance of the called component. Such a structure |
| * usually contains all variables, data or state information a component member |
| * needs for operation. The address of the upper instance must be known by |
| * the lower (completing) instance. The mechanism to ensure that this |
| * information is present involves the structure phFriNfc_CplRt_t . See its |
| * documentation for further information. |
| * |
| * Second Parameter: Status Value |
| * The lower layer hands over the completion status via this parameter. The |
| * completion routine that has been called needs to process the status in a way |
| * that is comparable to what a regular function return value would |
| * require. |
| * |
| * The prototype of the component's Process(ing) functions has to be |
| * compatible to this function pointer declaration for components interacting |
| * with others. In other cases, where there is no interaction or |
| * asynchronous processing the definition of the Process(ing) function can |
| * be arbitrary, if present at all. |
