How to use __uuidof in MINGW?

Question

I want to use __uuidof in function CoCreateInstance:

CoCreateInstance(clsid,NULL,CLSCTX_INPROC_SERVER,__uuidof(Isesoft),(LPVOID*)&pem);

error:

'__uuidof' was not declared in this scope.

How can I use it in MINGW?

Answer 1

__uuidof is an MS specific extension, but you should be able to replace __uuidof(IMyInterface) with IID_IMyInterface for the same behavior in a portable way.
