Consider the following code, where channels are used to synchronize threads as they add a stream of values. Assume read_input() will always return a uint64_t value and also assume that channel_send and channel_receive are implemented correctly. 1. // global channel 2. channel_t* channel; 3. 4. // receives two values from channel then sends their sum on the same channel 5. void* work(void* arg) { 6. uint64_t x; 7. uint64_t y; 8. for (int i = 0; i < 9; i++) { 9. channel_receive(channel, &x);10. channel_receive(channel, &y);11. channel_send(channel, x + y);12. }13. return NULL; 14. }15. 16. int main() {17. channel = channel_create(3);18. 19. // create a thread to run the work function20. pthread_t thread;21. pthread_create(&thread, NULL, work, NULL);22. 23. for (int i = 0; i < 10; i++) {24. uint64_t value = read_input();25. channel_send(channel, value);26. }27. 28. pthread_join(thread, NULL);29. 30. uint64_t result;31. channel_receive(channel, &result);32. printf("Final sum: %lu\n", result);33. return 0;34. } Describe a specific thread ordering that will lead to a deadlock. In your example, make sure to include any conditions needed for the deadlock to show up (e.g., a specific number of messages in the channel).
