The simple way is just to define your function with two parameters.
The first one is a pointer to the array. The second one is the array size
in bytes, or the number of bytes that you want to be processed in the
array. In other words, you pass the size along with your array pointer.

Covers why the called function can't know the 'size' of what is passed, without this being also sent.
