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))
