hi
i like to implement for our application a plugin system. Which allows user
to implement their own plugins, dynamic libraries. I have some question
(conceptionals):
(1) If the user build against a elder OSG version, would the plugin still
run if we would change our OSG version, means the main application will
change the version, the plugin not. we will pass
a pointer of osg::Node*. the node* is of version XXX.XXX.2 and the
plugin use version XXX.XXX.1 means an elder version. and the plugin just
knows the elder interface, it sould run, or i am wrong?
(2) under windows i can ask for a void* pointer to an function pointer, with
the handle and static name (string) is this a good choose, alos respect to
platform portability?
example :
------------------------------------
HMODULE module = LoadLibrary(dll_name.c_str());
if ( module ){
void* addr = (void*)GetProcAddress( module, "createDLL" );
if ( addr ) {
// Def. function parameters
typedef void ( *CreateFn)( void* );
CreateFn pfnCreate = (CreateFn) addr;
pfnCreate(m_Object);
}
}
thanks a lot
