linux - How do I find the maximum stack size?

Question

I am working on Ubuntu 11.04. How do I find out the maximum call stack size of a process and also the size of each frame of the stack?

Answer 1

You can query the maximum process and stack sizes using getrlimit. Stack frames don't have a fixed size; it depends on how much local data (i.e., local variables) each frame needs.

To do this on the command-line, you can use ulimit.

If you want to read these values for a running process, I don't know of any tool that does this, but it's easy enough to query the /proc filesystem:

cat /proc/<pid>/limits
