I have no sympathy for Ronald Cole's position in this thread.
But I want to pick a nit with one comment that Robert Dewar made.

That's not correct. The ANSI/ISO C standard dictates behaviour, not
implementation. C implementations can implement pass-by-value by
passing a pointer and then making a copy in the callee if and only if
the address of the struct is taken or the struct is modified.
