How the host will load a Plug-in

The host application will handle a Plug-in in the following manner (some code is Windows-specific!):

HMODULE hModule = LoadLibrary ("SomePlugin.dll");
if (hModule)
{
InitModuleProc initProc = (InitModuleProc)GetProcAddress (hModule, "InitDll");
if (initProc)
{
if (initProc () == false)
{
FreeLibrary (module);
return false;
}
}
GetFactoryProc proc = (GetFactoryProc)GetProcAddress (hModule, "GetPluginFactory");
IPluginFactory* factory = proc ? proc () : 0;
if (factory)
{
for (int32 i = 0; i < factory->countClasses (); i++)
{
PClassInfo ci;
factory->getClassInfo (i, &ci);
FUnknown* obj;
factory->createInstance (ci.cid, FUnknown::iid, (void**)&obj);
...
obj->release ();
}
factory->release ();
}
ExitModuleProc exitProc = (ExitModuleProc)GetProcAddress (hModule, "ExitDll");
if (exitProc)
exitProc ();
FreeLibrary (hModule);
}
Empty
