| 14.1 | What happens in Figure 14.1 when we reset the signal handler, and the process has not established a handler for SIGALRM? |
| 14.2 | In Figure 14.1, we print a warning if the process already has an alarm timer set. Modify the function to reset this alarm for the process after the connect, before the function returns. |
| 14.3 | Modify Figure 11.11 as follows: Before calling read, call recv specifying MSG_PEEK. When this returns, call ioctl with a command of FIONREAD and print the number of bytes queued on the socket's receive buffer. Then, call read to actually read the data. |
| 14.4 | What happens to the data in a standard I/O buffer that has not yet been output if the process falls off the end of the main function instead of calling exit? |
| 14.5 | Apply each of the two changes described following Figure 14.14 and verify that each one corrects the buffering problem. |
