如信号(7)的手册页中所述, Interruption of system calls and library functions by signal handlers
If a signal handler is invoked while a system call or library function call is blocked, then either:
* the call is automatically restarted after the signal handler returns; or

在这方面,我是初学者的定义。我需要为一个类安装virtualbox,我迷路了。首先,我在chromebook上安装了Linux。我输入virtualbox,它会打开,但我收到消息,

Please install the virtualbox-dkms package and the appropriate headers, most likely linux-headers-geab5e6346fdb.
You will not be able to start VMs until this
我正在寻找一种在linux主机上的朱莉娅脚本中捕获SIGINT的方法,但我无法理解如何管理信号。
在REPL中:
julia > try
sleep(1000)
catch e
@info "interrupt captured!"
end
Ctrl-C
[ Info: interrupt captured!
相反,执行demo.jl
try
sleep(1000)
catch e
@info "interrupt captured!"
end

terminal> julia demo.jl
Ctrl-C
s
我正在Linux中做C程序。我有一个主线程,它连续更新两个变量的值,其他线程每20毫秒将这些变量值写入文件中。我利用睡眠来达到这个时间间隔。示例代码如下。

pthread_create(...write_file..); /* started another thread by passing a function write_file */
while(variable1)
{
updates value of variables
}
return 0;
}
void write_file()
{
