One of the major differences between K&R and ANSI C was this exact point.
In K&R you couldn't pass a structure as an argument. You could pass a
pointer
to a structure but not the structure itself. In ANSI C you *can* pass a
structure: either as a parameter or a return value.
The comment about large structures resulting in a lot of data being pushed
onto the stack is very true. This is why in C++ you can pass a reference,
and ideally a "const reference".
