On success, the thread ID of the child process is returned in the caller's thread of execution. 没错, clone() 出来的东西, 必定表现为系统中的一个新线程, 但不一定表现为系统中的一个新进程, 所以 clone() 必须强调其返回值是个 thread ID. [20240208.2e] 在
C程序仅从父进程id获取子进程id (minix) 、 这必须是用C写的。我用mproc得到了一个子进程pid的父进程,并列出了某个索引中的所有进程,但我不能从那个跳到这个。pid of this process printf("Child pid for ppid %d is %d\n",int idx = 0;while (mproc[idx].mp_pid) 浏览6提问于2016-12-17得票数...
