The interpretation of these function implementations seems to be reasonable. Would you like to achieve any improvements for the corresponding software documentation? > So Don't need to check input clock parameters before calling clk API. What do you find imperative in this wording? Another wording alternative: Thus omit extra null pointer checks before four function calls. Regards, Markus
