It's part of it, but not the whole of it, and early C compilers had no
information about the parameters except from the call site itself. You
could even call the same function multiple different ways (this was
later formalized with variadic functions).
Back to that old Whitesmith's compiler. It's certainly very interesting
to see what the assembler looks like when you forget the ampersand, the
compiler doesn't throw an error, and so the entire structure instead of
a single pointer gets passed into your function. Not so much passed by
value, or reference, or object, but complete foul up :)
