As I pointed out earlier, C
NEVER passes arguments by reference.
There is only one (kind of) exception to this rule, that is:
the name of a vector is always the same as the address of its first
element,
that is
if x is a vector, then x is the same as &x[0],
so if you pass x (a vector) to a function, the address of the vector is
passed to the function.
This is not true for structures, where the whole structure is passed by
value,
that is, copied into the argument list.
But again: the equation (x the same as &x[0]) is not limited to function
calls,
it is true everywhere.

earlier point in this thread that C invariably passes
arguments by reference.
As usual, the simple answer is 'it depends' and, as Shmuel
points out, the devil is in the details.
