Macro quote expansion

[Skute]

Hi,

is it possible to get quotes inside a macro??

basically i want to change this:

#ifdef PEGASUS_EXPORTS
#define PEGASUS_API __declspec(dllexport)
#else
#define PEGASUS_API __declspec(dllimport)
#endif

to this:

#ifdef PEGASUS_EXPORTS
#define PEGASUS_API extern "C" __declspec(dllexport)
#else
#define PEGASUS_API extern "C" __declspec(dllimport)
#endif


Obviously the second macros give compiler errors.

Thanks

ok ive since discovered that it isnt the define which is the problem, its the expansion in the class definition

class PEGASUS_API Cpegasus
{
public:
Cpegasus();
};

That generates a load of errors, but seems to work ok when extern "C" isnt included. im guessing thats because you cant have classes in C.

I can access exported functions from an unmanaged C++ DLL in C#, but i want to be able to access an unmanaged C++ class. Also i have a problem of any global variables that are declared in the DLL cause my application to stop responding. If i define a global variable:

CIMClient client;
void Connect();
void Disconnect();

It stops the app from responding, any ideas?
