I apologize.  Here's how that message was supposed to read:

Having gone back and re-read what Scott said, I now see and agree with your
point, Bruce.  But I also agree with Scott: from a performance standpoint it
is usually better to pass a pointer to a structure than it is to pass the
structure itself in c, especially if the structure is large.  When you pass
the pointer, you are passing by reference.

Consider, for example, the FILE structure, and how we use it. 

For reference: http://archive.midrange.com/midrange-l/201002/msg00269.html
"the vast majority of structures I've seen used in C are passed by
reference."
