C中多个例子
原标题:Multiple Fork example in C

I am trying to have a program that uses multiple forks.
I used this example to get myself started Multiple fork() Concurrency

它是完美的。 然而,当我试图在儿童身上添加一个这样的文字:

 if ((p = fork()) == 0) {
          // Child process: do your work here
        printf("child %i
", ii);
          exit(0);
       }

这一进程从未结束。 我如何在儿童身上打脚,让父母们继续完成方案的执行?

最佳回答

阁下的榜样

if (waitpid(childPids[ii], NULL, WNOHANG) == 0) {

应当

if (waitpid(childPids[ii], NULL, WNOHANG) == childPids[ii]) {

因为

等待:在成功之后,回到了国家已经改变的儿童的身份证;在错误中,1人已经返回;如果《WNOHANG》被具体指明,而且没有《出生证》具体规定的儿童(伦)已经改变,则0人返回。
