关于过程的pid [英] About the pid of the process

问题描述

我有一个愚蠢的问题，如果我创建了一系列流程...这些不一定是某种继承，则流程的pid必须是数字连续的或随机的pid?

I've a somewhat silly question, if i have a series of processes that are created ... these are not necessarily some sort of inheritance, the pid of the processes have to be numbers continuous or random pids ?

推荐答案

这由操作系统决定.

通常，它们通常由OS顺序分配.但是，此行为不是要依据的行为，因为大多数操作系统规范都指出进程ID的分配不是确定性的(即:它可以是随机的，并且可以在将来的版本中进行更改，等等).

In general, they are usually sequentially assigned by the OS. However, this behavior is not something to base decisions upon, since most operating system specifications state that the process ID allocation is not deterministic (ie: it could be random, and could change in a future version, etc).
