May I ask one more question: why a code like this would work in
D-application but not in D-DLL? (also I notice some other D
functions don't work in DLL):
Probably because the runtime not initialized properly. Export an
Initialize() and Terminate() functions and call them from your
application loading the dll.
Inside those functions:
export extern(C) void Initialize() {
import core.runtime;
Runtime.initialize();
}
export extern(C) void Terminate() {
import core.runtime;
Runtime.terminate();
}
If you call those the other functions should start working.
(this is a fairly common thing libraries need to do, but it might
be tricky if you are loading the dll into an uncooperative
application, there's other hacks for that, but having your
functions like this and the app calling them are the right way to
do it)
