You clearly are not a C programmer.

Most of my C data abstractions use dual circular linked lists of 
pointers to structures of pointers. *All* of that is only ever passed 
(at least in my programming) as references. My code almost never passes 
data by value.

We do not consider passing a pointer as *by value* because its an 
address; by definition, that is pass-by-reference. We are not passing 
the *value* of the data, we are passing the memory location (the 
reference) to the data. Pass by *value* on the other hand actually 
places the *value* of the data item on the call stack as a parameter.

Much of this conversation has more to do with semantics.

kind regards,
m harris
