I don't think there's a contradiction. The declaration on the structure is the default for the members and applies to the vtable and other class data. There's no reason the members shouldn't be implemented elsewhere, and there's certainly existing code (in Windows, SymbianOS, and other DLL-based operating systems, whether or not there is on GNU/Linux) that implements different class members in different DLLs, while still not exporting the class from its home DLL. One situation where this is useful is when the class members are actually shared between multiple classes, or are also callable as C functions, etc. -- Mark Mitchell CodeSourcery [EMAIL PROTECTED] (650) 331-3385 x713
