On the language level, that's passing a pointer to an array object.
The pointer itself is passed by value.  Passing a pointer to an array
is conceptually no different than passing a pointer to anything else.

C has pass-by-reference in exactly the same way that it has
linked lists.  It has neither as a language feature, but both can
be emulated using pointers.  And you can't really understand how
C handles arrays if you start by asserting that they're "passed
by reference".

But you just have to make it seem more complicated than it really is.
