Description David Rothlisberger 2010-04-29 20:12:55 UTC I know that dozens of bugs have been opened for this over the years, but please read this through. If you have a C++ program missing a return statement from a function that is supposed to return a value, g++ will compile it happily with no errors (or even a warning, unless -Wreturn-type or -Wall in function returning is used). Trying to use the return value from the function will most likely cause a segmentation fault. Dozens of bugs have been opened for this over the years (e.g. bug 11474), all rejected as invalid based on the following statement from section 6.6.3 of the C++ standard: Flowing off the end of a function is equivalent to a return with no value; this results in undefined behavior in a value-returning function. However, the very same paragraph begins with: A return statement without an expression can be used only in functions that do not return a value, that is, a function with the return type void, a constructor (12.1), or a destructor (12.4). In my opinion, the standard contradicts itself. Either flowing off the end of a function is "equivalent to a return with no value" (i.e. invalid according to the beginning of the paragraph) or it is "undefined behaviour". It can't be both. Appendix C is informative rather than normative, but can help us understand the intent of the standard. Section C.1.4 says: Change: It is now invalid to return (explicitly or implicitly) from a function which is declared to return a value without actually returning a value. Rationale: The caller and callee may assume fairly elaborate return-value mechanisms for the return of class objects. If some flow paths execute a return without specifying any value, the impleme

Re: return-statement with a value, returning 'void' #2 Jul 30, 2012, 11:41 pm 'void' means doesn't have a type. You cant return a variable from a void function.You also have to declare variables that you are sending to a function, i.e: tuneWord Essentially, you have declared your function as:void convTuningWord(void);Which means you can neither pass a variable to it, nor return one.Perhaps this is what you mean:Code: [Select]
someReturnType convTuningWord(someType tuneWord) {
someReturnType freq = ((CLK*tuneWord)/TUW); //converts tuning
return freq; //word to frequency
}Where 'someType' is whatever tuneWord is (e.g. float, int, long), and 'someReturnType' is whatever type freq is (e.g. float, int, long). I cant tell from the code you have posted what they should be.Alternatively, if freq and tuneWord are global variables, you can just do this:Code: [Select]
void convTuningWord() {
freq = ((CLK*tuneWord)/TUW); //converts tuning
return; //You dont need to return anything as freq is stored globally anyway
