Irrlicht source question

[Halifax]

I have looked at tutorials on how to build DLLs etc. and they all say you need to have __declspec(etc.) before every class/function you want exported.

I have run grep *.* through the Irrlicht directory and it returns only 3 finds for __declspec()

How can Irrlicht work as a DLL if it doesn't have these?

[vitek]

All exporting does is tell the linker that the function needs to be callable from outside the DLL. Everything else is either inline or accessable from the object returned from the exported function.

But still there isn't __declspec(...) before every class exported..?
I see only createDevice/Ex has it.

Code: Select all

00158 #ifdef _IRR_WINDOWS_API_
00159 
00160 #ifndef _IRR_STATIC_LIB_
00161 #ifdef IRRLICHT_EXPORTS
00162 #define IRRLICHT_API __declspec(dllexport)
00163 #else
00164 #define IRRLICHT_API __declspec(dllimport)
00165 #endif // IRRLICHT_EXPORT
00166 #else
00167 #define IRRLICHT_API
00168 #endif // _IRR_STATIC_LIB_

Code: Select all

IRRLICHT_API IrrlichtDevice* IRRCALLCONV createDevice(
00278                 video::E_DRIVER_TYPE deviceType = video::EDT_SOFTWARE,
00279                 const core::dimension2d<s32>& windowSize = (core::dimension2d<s32>(640,480)), // paranthese are necessary for some compilers
00280                 u32 bits = 16,
00281                 bool fullscreen = false,
00282                 bool stencilbuffer = false,
00283                 bool vsync = false,
00284                 IEventReceiver* receiver = 0,
00285                 const c8* sdk_version_do_not_use = IRRLICHT_SDK_VERSION);
00286 
00288 
00295         IRRLICHT_API IrrlichtDevice* IRRCALLCONV createDeviceEx(
00296                 const SIrrlichtCreationParameters& parameters);

Because that's the only function which can be called from outside. All other methods need to go via the device.

[rogerborg]

Yup. (On Windows) run depends on any of the DirectX Dlls and see how few symbols they actually export.

[Halifax]

Oh I get it now, so basically all those getter functions in the device stop the need for you to export those classes explicitly?
