gcc error statement with no effect Vestal, New York

As for flipping the state, !(options -> updateStatus) is just a test (so to speak) to determine if options -> updateStatus is true or false. Just arbitrarily removing code that makes a compiler complain is not good practice. It goes (initiation ; loop condition ; iteration).

So the comma expression is actually part of an abandoned parameter list. The for loop works like this: for (initial value, if any ; condition for repeating the loop ; action at end of loop) because you had it out of order, thusly:

Make sure currentDirection is assigned to a valid value or it might have garbage and might later cause issues. I am obligated to say that the way to suppress these warnings is to correct the source code that is triggering them. There's no "delay_sec=0" code in pomprocker's code; Your brain sees it because you expect it in the begining of the for statement, but there's no such thing. of the atom whose 1s electron moves nearly at the speed of light?
