- 此程序在运行的时候,产生一个子进程.此子进程每隔1秒钟,向父进程发送一个SIGUSR1信号,父进程收到信号后,打印当前系统时间.当经过10秒钟后,子进程结束运行,并发送SIGUSR2信号,通知父进程 父进程收到SIGUSR2信号后,退出.-this program in running time, have a child process. This process for every one seconds, father proce

- 利用管道技术实现父子进程间通信，具体流程：父进程以3秒为周期接收用户输入并发送到子进程，子进程接收到信息后显示并回传，父进程接收到回传信息后显示。父子进程在通信过程中采用信号中断处理方式进行处理，接收到“exit”字符串后父子进程均退出。（提示，采用SIGUSR1或SIGUSR2信号）-The use of pipeline technology communication between parent and child, the s

- perf_evlist__prepare_workload will send a SIGUSR1 if the fork fails, since we asked by setting its exec_error to this handler.
rlogin
- will use SIGUSR1 for window size hack, so hold it off.
