Unless the property you're accessing is also a pointer property,
like
sizeof. Then you have to be careful. The below prints 4 then 8
(on 32-bit):
unittest {
import core.stdc.stdlib : malloc, free;
struct Foo
{
public int bar, baz;
}
auto foo = cast(Foo*)malloc(Foo.sizeof);
import std.stdio;
writeln(foo.sizeof);
writeln((*foo).sizeof);
free(foo);
}
Do pointers have any other cases like this besides 'sizeof'?
I couldn't find a list of pointer properties in the docs (whereas
I know
where the list of array properties is).
