Back in the days of K&R, Kernighan and Ritchie published an addendum
to the "C Reference Manual" titled "Recent Changes to C" (November 1978)
in which they detailed some differences in the C language post "The
C Programming Language".
The first difference they noted was that
"Structures may be assigned, passed as arguments to functions, and
returned by functions."
From what I can see of the ISO C standards, the current C language
has kept these these features. However, I don't see many C projects
using them.
I have a project in which these capabilities might come in handy; has
anyone had experience with assigning to structures, passing them as
arguments to functions, and/or having a function return a structure?
Would code like
struct ab {
int a;
char *b;
} result, function(void);
if ((result = function()).a == 10) puts(result.b);
be understandable, or even legal?
