[Date Prev][Date Next][Thread Prev][Thread Next] [Date Index] [Thread Index]

While the current behavior may seem unintuitive at first sight, I think it is very sane. A function can return 0, 1 or multiple values even in the same function. I often return an error status as first value and if that indicates success, more values can follow. Without the current behavior, the parameter assignment to a printf() style function would change at runtime depending on the outcome of the function call and that would be much more confusing and error prone than this clear and comprehensive behavior.
