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?

 
Typically this is fine.  However, in sdcc-4.2 manual one can find
the following statement:
 
: Deviations from standard compliance:
:   structures and unions cannot be passed as function parameters
:   and cannot be a return value from a function,....

Not a problem. I don't foresee that the code I'm working on would be
compiled with a non-standard C compiler (assuming that I've read
the standards correctly wrt struct pass-by-value).
