i've been googling this, and i've found nothing. i recall seeing const used like this (either c or c++, not sure): 

int func(void) const
{
    return 0;
}
what does that mean?

A const object can use the function and gaurantee that its guts won't be changed.
That is, if it is a member function (which I assume it is).

Or something like that.

It means that the function (which is, BTW, a member function of a class) promises not to change the data in the instance of the class. Which means you can call it even if you have an instance of the class which you're not allowed to change. More info.
