Sorry for the incovenience. The M$ compiler docs claim this construct to be correct (there is no warning at all for the redefinition and at least for C++ this is standard conform :) See : http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vclang98/ht ml/_pluslang_redeclaration_of_typedef_names.asp >Should the lines like > >typedef struct _DiaRenderer DiaRenderer; > >be replaced by matching #include statements? > this would give the 'circular header dependencies', e.g. object.h needs to include diarenderer.h and vice versa, which I tried to avoid. IMO the best solution would be a dia-types.h file only to define the common typedef's something like #ifndef DIA_TYPES_H #define DIA_TYPES_H typedef struct _Layer Layer; typedef struct _DiagramData DiagramData; typedef struct _DiaRenderer DiaRenderer; #endif This would allow to pass partly known 'class' pointers without exposing any details of the concrete class definitions. What do others think about this ?
