I suggest to add comment in the code explaining the reason behind putting value in the pointer, as it not trivial

[amgross]

I think you wrote the word 'in' twice by mistake " 0 can be valid value or in in case of error."
Anyway I thought we agreed in the issue discussion that this solution is not enough?

[Hadatko]

HI @amgross , the last commit was related to your request with adding comment to code.
Final decision was not made related to memcpy. But as i said, i will likely add if condition.

[Hadatko]

@amgross what do you think about memcpy_s?

[amgross]

@Hadatko I think memcpy_s will solve the issue. unfortunately it seems from the documentations that not all compilers includes this function.
'As with all bounds-checked functions, memcpy_s is only guaranteed to be available if STDC_LIB_EXT1 is defined by the implementation'

@amgross Thank you for your collaboration.

@MichalPrincNXP likely ready.
