Various techniques for returning multiple values include: Returning a tuple of values. This is conventional in languages (such as Python) that have a built-in tuple data type and special syntax for handling these: in Python, x, y = f() calls the function f returning a pair of values and assigns the elements of the pair to two variables ...
In a statement such as while ((ch = getchar ())!= EOF) {…}, the return value of a function is used to control a loop while assigning that same value to a variable. In other programming languages, Scheme for example, the return value of an assignment is undefined and such idioms are invalid.
In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp. If a function has the return type void , the return statement can be used without a value, in which case the program just breaks out of the current function and ...
POD return values 33–64 bits in size are returned via the EAX:EDX registers. Non-POD return values or values larger than 64-bits, the calling code will allocate space and passes a pointer to this space via a hidden parameter on the stack. The called function writes the return value to this address. Stack aligned on 4-byte boundary. stdcall ...
