In addition to tagging, you can also look into whether true_typedef is suitable. Matthew Wilson's STLSoft has an implementation.

true_typedef seems like a really good choice. I'm unclear what the STLSOFT_GEN_OPAQUE macro really provides. The macro is defined as follows. #define STLSOFT_GEN_OPAQUE (type) typedef struct __stlsoft_htype##type{ int i; } const* type; So to use the STLSoft version I have to use the macro and then provide the typedef. It would look like this. STLSOFT_GEN_OPAQUE (ConfigName_u) typedef stlsoft::true_typedef ConfigName; How is this better than just declaring a struct in the typedef itself. It would look like this. typedef stlsoft::true_typedef ConfigName; What does having a pointer to a struct provide that a normal struct doesn't? Ryan
