Description: Signal Processing Experiment 4 (20 points)
purpose:
Learning and mastering signal processing methods, particularly the use of sigaction, alarm, sigpending, sigsetjmp and siglongjmp and other functions.
Claim:
1, the preparation of the execution time limit with a simple function of shell:
myshell [-t <time>]
This functional test procedures similar to Experiment 1, but with the system shell (on cs8 server is bash) for full functionality. <time> is the test program allows users to command execution time limit, the default value is unlimited. When the user commands the execution time limit is reached, test the program terminates user commands instead receive the next user command.
2, myshell only run in the foreground.
3. Press Ctrl- \ key is not interrupted run myshell program, but the current interruption receiving user commands or terminate execution of the current user commands instead receive the next user command.
4, deal with the relationship between nested at
