In a project using a server.dll and a client.exe, I have dllexport
ed a server symbol from the server dll, and not dllimport
ed it into the client exe.
Still, the application links, and starts, without any problem. Is dllimport
not needed, then???
Details:
I have this 'server' dll:
// server.h
#ifdef SERVER_EXPORTS
#define SERVER_API __declspec(dllexport)
#else
#define SERVER_API // =====> not using dllimport!
#endif
class SERVER_API CServer {
static long s;
public:
CServer();
};
// server.cpp
CServer::CServer(){}
long CServer::s;
and this client executable:
#include <server.h>
int main() {
CServer s;
}
The server command line:
