          goto is generally frowned on by programmers.

           

          The only legitimate use of goto is when you need to escape a nested loop.

           

          If you need to skip part of a routine, use break, or simply return from the current function.

           

          The pattern commonly used by the SDK looks like this:

           

          do
          {
               if(condition1 == false)
                    break;
               if(condition2 == false)
                    break;
               if(condition3 == false)
                    break;
               doSomethingReallyCool();
          }while(false);
          

           

          "break" jumps to the end of the do/while loop which always exits when you reach the end of it (while(false))
