Unloads any DLLs that are no longer in use and that, when loaded, were specified to be freed automatically.
void CoFreeUnusedLibraries( );Applications can call CoFreeUnusedLibraries periodically to free resources. It is most efficient to call it either at the top of a message loop or in some idle-time task. DLLs that are to be freed automatically have been loaded with the bAutoFree parameter of the CoLoadLibrary function set to TRUE. CoFreeUnusedLibraries internally calls DllCanUnloadNow for DLLs that implement and export that function.
