A netwоrk device driver implemented using а Mesа-style mоnitоr will trаnsmit two packets at a time. Whenever a packet arrives, it will call APacketArrives(). When there are two packets, it will call Send2Packets(); Assume that we have an even number of packets. Does the following code work? (1pt) If so, please prove the correctness. If not, please show execution steps to show why it does not work (4pts). 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. int nPackets = 0; Lock lock = new Lock(FREE); Condition okToSend = new Condition(&lock); void APacketArrives() { lock.Acquire(); nPackets++; lock.Release(); if (nPackets < 2) { lock.Acquire(); okToSend.wait(&lock); lock.Release(); } else { lock.Acquire(); Send2Packets(); nPackets = 0; okToSend.signal(&lock); lock.Release(); } }
