c - Vfork() 和更多腐败

Question

我的问题是执行时父堆栈会发生什么？

main()
{
    f();
    g();
}
f()
{
   vfork();
}
g()
{ 
    int blast[100],i;
    for(i=0;i<100;i++)
        blast[i]=i;
}

Answer 1

根据 http://pubs.opengroup.org/onlinepubs/009695399/functions/vfork.html 未定义该行为

the behavior is undefined if the process created by vfork() [...] returns from the function in which vfork() was called [...]
