Thread: Global object inside windows DLL: When gets the DTOR called?

Hi,

I compiled this class in a DLL:

Code:

class DbQuery :boost::noncopyable
{
	DbQuery();
	~DbQuery();
	pthread_mutex_t mQueryMutex;

public:

	inline static DbQuery& instance()
	{
		static DbQuery db_query;
		return db_query;
	}

[...]

};

It's used by several processes and encapsulates the access to a database. DB is opened in CTOR and closed in the DTOR. But when does the DTOR gets calles in this case? Never? Or if no process is using it any more in windows decides to unload the DLL (does this mechanism even exist?)?

Thank You!

Global object constrcutors and destructors are called within the context of DllMain(), so you have to follow allow the rules and restrictions of what you can and can't do inside DllMain().
