Declspec Macro Example

["David Haney" <haney@roguewave.com>]

The following is some code demonstrating how I’ve seen Microsoft declspec handling for classes and functions in the past.  The definitions usually occur in a separate header. 

 

#if LIB_BUILD

#  define DECLSPEC __declspec(dllimport)

#  define DECLSPEC_FUNC(ReturnType) __declspec(dllimport) ReturnType

#else

#  define DECLSPEC __declspec(dllexport)

#  define DECLSPEC_FUNC(ReturnType) __declspec(dllexport) ReturnType

#endif

 

class DECLSPEC Foo {

  Foo();

};

 

DECLSPEC_FUNC(int) fooFunc(void) {}
