Ugly. Rather, if we were to pass an extra parameter through the entire callchain, I'd rather see that parameter to be what to do when we see an error. Depending on that, the callee can die(), return error(), or silently return -1, or do something else. I really do no think it is a good idea to pass text string back to the caller, which invites sentence lego and untranslatable mess.
