How to use return values

Really simple question, can't seem to find an answer. How do I do anything with a return value from a function. For example, I want to check the value of the return value with an if statement, what is the name of that which I should be comparing?

Code:

---

void something (blah, blah2)
{
  ...some code here...
  return 5;
}

int main()
{
  something (5, 7);
  if ( ??? == 5)
    {
    ...some code here...
    }
}

First of all your type signature is wrong for returning an integer. Try

Code:

---

int something (int a, int b) { return(5) ; }

---

Second you have to have a variable to receive the output of your function (in most cases).

Code:

---

int y = something(5,7) ;
if (y == 5)
{

}

---

You should give your C book a read now and then, or even try some of the tutorials.

I was just painting in wide strokes so I forgot to add the types.

Putting a variable to capture the return value is what I was looking for. Thanks!

or

Code:

---

if (something(5, 7) == 5) {
...
}
