See return value in C#
Hi, Consider the following piece of code: As you can see we are on line 28. Is there any way to see the return value of the function at this point, without letting the code return to the caller function? Foo.Bar() is a function call which generates a unique path (for example). So it's NOT constant. Entering ?Foo.Bar() in the immidi...
Scala return type for tuple-functions
Hello Guys, I want to make a scala function which returns a scala tuple. I can do a function like this: def foo = (1,"hello","world") and this will work fine, but now I want to tell the compiler what I expect to be returned from the function instead of using the built in type inference (after all, I have no idea what a (1,"hello","w...

Java return to position N in call stack.
Using the return keyword in Java code will return execution to the last piece of calling code in the call stack. If object foo calls baz.bar(), the return keyword in the bar method will continue code execution in foo. Let's say I have object foo that calls foofoo that calls foofoofoo in the above scenario, and foofoofoo calls baz.bar()....
Is return an operator or a function?
This is too basic I think, but how do both of these work? return true; // 1 and return (true); // 2 Similar: sizeof, exit My guess: If return was a function, 1 would be erroneous. So, return should be a unary operator that can also take in brackets... pretty much like unary minus: -5 and -(5), both are okay. ...
Return statements for all functions
How common is it for coding style guidelines to include a requirement that all functions include at least one return statement (even functions which return void)? To avoid being subjective or argumentative, I'd like answers which can name specific companies or open-source projects which have this requirement. If you haven't ever come ac...

Is it possible to return a list of numbers from a Sybase function?
I'm trying to overcome a very serious performance issue in which Sybase refuses to use the primary key index on a large table because one of the required fields is specified indirectly through another table - or, in other words; SELECT ...

C++ Returning Pointers/References
I have a fairly good understanding of the dereferencing operator, the address of operator, and pointers in general. I however get confused when I see stuff such as this: int* returnA() { int *j = &a; return j; } int* returnB() { return &b; } int& returnC() { return c; } int& returnC2() { int *d = &c; return *...
C# function normal return value VS out or ref argument
I've got a method in C# that needs to return a very large array (or any other large data structure for that matter). Is there a performance gain in using a ref or out parameter instead of the standard return value? I.E. is there any performance or other gain in using void function(sometype input, ref largearray) over largearray fun...
Can a constructor return a NULL value?
I know constructors don't "return" anything but for instance if I call CMyClass *object = new CMyClass() is there any way to make object to be NULL if the constructor fails? In my case I have some images that have to be loaded and if the file reading fails I'd like it to return null. Is there any way to do that? Thanks in advance. ...
