NTSTATUS DoSomething()
{
   NSTATUS Status = NtXXX();
   if (NT_SUCCESS(Status)) {
       Status = NtYYY();
       if (!NT_SUCCESS(Status))
           cleanupXXX();
       Status = NtZZZ();
       if (!NT_SUCCESS(Status))
           cleanupYYY();

   }
   return Status;
}

i think thats the most simple and easy to read
but in the end is´ent it not a littel waste of time
discusse old functions their need rewrite anyway..?
