我知道这是一个新问题,但我的理解是,现在的父母程序将预示一个与父母完全相同的新的儿童进程,这意味着儿童也应为儿童进程而奋斗。 实际上,这只会产生一个儿童进程。 我无法理解儿童将执行什么法典?

儿童过程开始在最后一名儿童离去的准确点执行,之后是静态发言。 如果你想永远放弃,那么你就不得不把它放在一旁。
正如每个人都提到的那样,儿童还开始在
You could see it clearly in the very common usage like this:
int main()
{
if (fork())
{
// you are in parent. The return value of fork was the pid of the child
// here you can do stuff and perhaps eventually `wait` on the child
}
else
{
// you are in the child. The return value of fork was 0
// you may often see here an `exec*` command
}
}
你们失去了一个半殖民地。
但是,儿童(以及父母)在《<<>fork>出现之后就继续工作。 从申请方案拟订的角度来看,fork
(如所有)为“atomic”。
两个过程(在<条码>后
如果儿童上电话fork
,则该儿童将有两个fork
(制作该编码的号码,然后制作的编号),而父母只有一人(带子女)。 <代码>fork 的性质是,一个程序称为该编码,两个程序从该文本中退回。
