-   or from a pointer to a function with a compatible type.
-   `pxSendCompletedCallback` and `pxReceiveCompletedCallback` are parameters to
-   `prvInitialiseNewStreamBuffer`. These two callback functions are not used when
-   `configUSE_SB_COMPLETED_CALLBACK` is set to 0.
+ - The pointer to function is casted into void to avoid unused parameter

+   not used.
