Exitting a void 'function' ?

Hello all...

Ive tried searchin the boards, but without much luck (mainly because peoples thread titles tend to suck at descriping what they are all about )

Well, my problem is this:

In a program I have to call a void 'function' (it's not really a function, but whats the other word? Procedure in VB ). In this 'function' I need to exit it at a certain point. Like:

if (cond)
exit void;

.. I don't know if this is possible though? I can't make it into an int function and just return 0 btw. Can anyone give me a hint?

Thx in advance

For a function with a 'return type' of 'void' just use 'return' if you need to; eg

Code:

int FunctionThatReturnsInt()
{
int the_answer=42;
return the_answer;
}

void FunctionThatDoesNotReturnAnything()
{
if (some_condition_is_met)
  {
  return;
  }
//function returns anyway
}

>it's not really a function, but whats the other word?
Procedure. But in C++, a function is a function, even if it doesn't have a return value.

>Can anyone give me a hint?
You can use return without an operand.

Code:

void foo()
{
  // stuff

  if ( condition )
    return;

  // more stuff
}

you could also only branch on the not true condition, and do nothing otherwise

hehe, can't believe I didnt try that myself xD

Thx ppl

Using return without operand will give you a compiler error on MSVC++ 2003. It's worth checking if it's legal as I know that the 2003 edition is pretty compliant to the standards.

It is completely legal and works fine in VC++ 2003. Perhaps you are thinking of using return; in a function that doesn't specify void as its return type.

Yes he MUST be!
