Just as the title says, is it safe to extern (C) variables?
Something like this:
extern (C) auto foo = 800;
And then call that from another program?
Also, just because this has been bugging me for a while.. Is
export broken, or it it not supposed to be used the same way
as extern (C)?
I wouldn't do it that way. I would use extern(C) with struct
and function definitions/declarations, but I don't think it
makes sense to use it with individual variables.
Not sure if anything is wrong with export, but they are two
different things. Export allows something to be visible to
other programs(like in a shared library) and extern is(I
believe) more so for specifying how something outside the
program is meant to be linked in.
My program is a shared library, and it uses extern (C) to let
other programs access the extern (C)'d functions and such.
Could you give me a definition of export, as I believe I may have
the wrong meaning and use of it.
The reason being, is that I did some test with something like
this:
export int test(string[] args)
{
return 0;
}
and the program trying to find it couldn't, I suppose that's
where I went wrong?
Back the main topic, thank you, I wanted to use it for variables,
but if it's not safe I'll use getters and setters, or maybe ref
or something. The reason I wanted to is because I'm using it as a
sort of settings.
