int Blah(x)
{
if(x == 5)
return 5;
if(x == 10)
return 10;
}
what happends if nothing is returned?

high,
say i have a funtion, called int Blah(x);
now, insidee Blah looks like this:
actually, I believe that most compilers will silently insert a ''return 0;'' at the end of the function in that case. If they don''t, then yes, you would get garbage.

Umh, what´s eax register? :o

registers are small one, two or four byte peices of memory directly inside the processor. That makes them the fastest possible memory, and the most expensive. eax is one of these on an x86 chip that is used to store the return value in the C calling convention.

Did you make sure to load eax with a bogus value before returning?
