It should be

int t = hLen + 1;

for (i = len - 1; i >= 0; i--) {

break;

}

 

: You should test the code, and think about the results here. For example, "ccw" is a routine which determines whether the winding is clockwise or counterclockwise. But from which side? Anyways... since that's not a documented issue... ccw should work regardless of the winding direction -- as long as the winding direction is consistent. So... you have encountered a real issue here. But it's probably not a code correctness issue -- it's probably a lack of adequate documentation issue (which is a frequent problem for coders).

: That said, taking a close look at the implementation, like you have done here, is great. We all-too-often have had errors in code here on this site -- often for very understandable reasons. So double checking results is frequently a good thing. Thanks!
