I dunno, in my experience if you see something worded the way this was:

    int something_init(const something_init_params* params);

the convention is that the params are temporary -- really just a way of passing a bunch of parameters to the init function. It would be a surprise that the params are expected to be static. E.g., the whole STM32 HAL is done this way, and it would be a disaster if you thought the init structs all had to be static!

BTW, you can see the assumptions of the non-embedded programmers talking about "taking ownership" being the default interpretation of a signature like that...if you don't have a heap, what does that even mean?

In any case, C is a mess, embedded is a mess, no argument there!

Making a copy is much less common in embedded if it's a large data structure.
