Certain people recommend that there be only one return

I have seen people enclosing the function logic inside a
while(1) merely to stick on to single return at the end.
while(1)
{
...
break; //otherwise return would come here.

break;
}
return ...;
In terms of code maintenance, multiple break statements have no
difference from multiple return statements. Those people are just
trying to deceive themselves.
