Is there anyway to find the PID of parent process without using getppid?
Question
我知道 PCB 是一个数据结构，其中包括父进程 id(pPID)、进程 id(PID)、指针等。有没有办法在不使用 getppid 函数的情况下找到父进程的 PID？

The fields of /proc/self/stat (as documented in proc(5) ) include PPID. Take care in parsing as comm may contain spaces and other unusual characters.
(But I second @JohnZwinck's comment. Why?)
