Ah, all right. Here's a SO thing (followed up by email then
Fortunately I am working with Win7, And the below function seems
to work beautifully.
export extern (Windows) void SayHello(Variant *Input_Variant)
{
string A = "HELLO WORLD!";
Input_Variant.CA_VariantSetCString(A.ptr);
}
My goal was to store variants in an associative array
Variant[string] and use this as a portable interpreter returning
the resulting Variant.
but that runs into some memory questions that I am not as savvy
with.
1. Memory:
I need to manage memory from the dll. I can give the caller a
pointer to manage, but I don't think that is visible from gc.
There should be different associtive arrays for different objects
in the caller. How do I manage this?
2. Threads:
I would like this to be as parallel as possible one objects call
to its data should not hinder anothers.
I have seen on the Memory managment page
http://wiki.dlang.org/Win32_DLLs_in_D but I would like to know
more.
