And you assume that I want to assign the error code to ret. Wrong. What if I

Assign it to ret and forward ret.

                           Or what if I want to return NULL beacuse the
function returns a pointer?

Bad design, fix it.

                                Using variables is complicated. Constants make
the code more simple and readable.

Simpler now, much more complex later to fix the incorrect error codes.

I think you want to force your preferred pattern to cases which clearly do not benefit from it. I still have to disagree. I suggest we make multilpe macros, and the user can decide which one to use.
