是否有在Linux进程的堆栈大小的限制 [英] Is there a limit of stack size of a process in linux

问题描述

是否有的Linux 在栈过程的大小有限制吗？难道仅仅依赖于机器的 RAM ？
我想，以限制递归调用的函数的深度知道这一点。

Is there a limit on the stack size of a process in Linux? Is it simply dependent on the RAM of the machine? I want to know this in order to limit the depth of recursive calls to a function.

感谢您。

推荐答案

堆栈通常是由资源限制的限制。您可以看到默认的设置是使用的ulimit -a 安装什么：

The stack is normally limited by a resource limit. You can see what the default settings are on your installation using ulimit -a:

stack size              (kbytes, -s) 8192

（这表明我的是8MB，这是巨大的）。

(this shows that mine is 8MB, which is huge).

如果您删除或增加限制，你仍然不能使用所有的RAM机器堆栈 - 堆栈从近进程的地址空间的顶部点向下生长，并在某些时候它将运行到code，堆或加载库。

If you remove or increase that limit, you still won't be able to use all the RAM in the machine for the stack - the stack grows downward from a point near the top of your process's address space, and at some point it will run into your code, heap or loaded libraries.
