You can't. Since the parameters are passed on the stack, you must rely on the code that is popping the parameters off the stack in order to get them passed. On top of that parameters can also be passed by pointers, where the pointer is pushed onto the stack and poped off by the function code, to be used to point to an area of memory that, unless you had the header file to describe it to you, would be utterly meaningless without any type of context.
