Question

Service::serviceCtlHandler(DWORD OpCode)
{
  //...
}

Service::ServiceStart
{
  //...
  serviceStatusHandle = RegisterServiceCtrlHandler("Service", &Service::serviceCtrlHandler /*incompatible*/); 
  //...
}

How do I get a compatible pointer?

Answer 1

You’ll need to make your serviceCtlHandler function static, which means it won’t be able to access any object members. This is because RegisterServiceCtrlHandler is expecting a function pointer which is not tied to an object and will not receive an implied this pointer.

If you use RegisterServiceCtrlHandlerEx instead, you can pass a pointer to the object and have the static function call another member function after properly casting the pointer.
