Linux Signal及Golang中的信号处理

Published at June 12, 2019 ·  1 min read

Linux 和 Golang 中的信号处理问题,在 Linux 中,则是操作系统中用来进程间通讯的一种方式,一个信号就是一个异步的通知,发送给某个进程,或者同进程的某个线程,当信号发送给某个进程时,操作系统会中断该进程的正常流程,并进入相应的信号处理函数执行操作,完成后再回到中断的地方继续执行。几个常见命令为,SIGINT 导致进程结束,SIGTSTP 导致进程挂起,SIGQUIT 导致进程结束 和 Dump core。在 Golang 中,则是通过 os/signal 和 syscall 捕捉到相应的信号量 Linux Signal及Golang中的信号处理...
