堆栈指针的打印出价值 [英] Print out value of stack pointer

问题描述

我如何在Linux操作系统（Debian和Ubuntu）？在C堆栈指针打印出当前值

How can I print out the current value at the stack pointer in C in Linux (Debian and Ubuntu)?

我试图谷歌，但没有发现任何结果。

I tried google but found no results.

推荐答案

一招，这是不可移植或真的连保证正常工作，就是简单的打印出本地的一个指针的地址。

One trick, which is not portable or really even guaranteed to work, is to simple print out the address of a local as a pointer.

void print_stack_pointer() {
  void* p = NULL;
  printf("%p", (void*)&p);
}

这将从根本上打印出 P 的地址，这是当前堆栈指针的一个很好的近似

This will essentially print out the address of p which is a good approximation of the current stack pointer
