I don't think that this alternative would buy us much and would add up to confusion. Remember that struct can only be declared once, so the definition of such a function then must look (syntactically) different from the prototype since it can't redeclare the struct. There can only be some marginal code base that uses struct definitions in prototypes directly. They are basically useless. So the C++ treatment would be a possible addition to C. Jens
