Hmm.. indeed.
It needs something..
Thank you for poining it.

Wow!! I didn't know this technique.
Indeed it can use NULL pointer.

But, I want to avoid "if (pos) else" code as much as possible,
and keep simple code.
It can handle all clk case without thinking it if it has null_clk.

Why you don't want null_clk ??

Thank you for your help !!

Best regards
