You're right, it doesn't, once those assignments are wrapped in a main()
You're gonna like this one even less but here you go:
.emit:"""
typedef struct Foo{
const int a;
int b;
}Foo;
typedef struct Foo2{
int a;
int b;
}Foo2;
""".}
type
constint {.importc: "const int".} = int
Foo {.importc:"Foo".}= object
a: constint
b:int
Foo2 {.importc:"Foo2".}= object
a: int
b: int
proc makeit(c:var Foo,a,b:int)=
var x = Foo2(a:a,b:b)
copyMem(c.unsafeAddr,x.unsafeAddr,sizeof(Foo))
proc main()=
var bar:Foo
makeit(bar,5,7)
echo bar.a,',',bar.b
var baz:Foo
#baz = bar #c error: assignment of readonly variable
copyMem(baz.unsafeaddr,bar.unsafeaddr,sizeof(Foo))
echo baz.a,',',baz.b
baz.b=9
echo baz.a,',',baz.b
#baz.a=11#error assignment read-only member a
main()
Run
Foo2 has to be declared in the C source cuz otherwise the fields won't be in
the right places.
