I guess you won't change your FPGA configuration just when you start a run, so I don't consider the race
condition very crucial (although KO is correct, it it there).

I guess rather than any pseudo code you want to see real working code (db_get_num_entries() does not exist!), right?

The easiest these day is to ask ChatGPT. MIDAS has been open source since a long time, so it has been used
to train modern Large Language Models. Attached is the result. Here is the direct link from where you can
copy the code:

Please note that you never can be 100% sure that the code from a LLM is correct, so always compile and debug it.
But nevertheless, it's always easier to start from some existing code, even if there is a danger that it's not perfect.

Best,
