What happens to global variables declared in a DLL?

Question

Let\'s say I write a DLL in C++, and declare a global object of a class with a non-trivial destructor. Will the destructor be called when the DLL is unloaded?

Answer 1

If you want to see the actual code that gets executed when linking a .dll, take a look at %ProgramFiles%\Visual Studio 8\vc\crt\src\dllcrt0.c.

From inspection, destructors will be called via _cexit() when the internal reference count maintained by the dll CRT hits zero.
