No.  In some C *implementations* they are placed on the stack in reverse
order.  In others they are placed on the stack in non-reverse order.  In
others they are passed in registers.  In yet others, different types of
arguments are passed in different kinds of registers.  An implementation
which uses registers will usually have to pass really big arguments on
an in-memory stack anyway.  And so on.  Use <varargs.h> or <stdarg.h>
(current practice and ANSI-C-draft practise respectively); they are the
*only* portable way to do this.
