栈回溯——获取当前线程内ebp与call_ret

开发环境：VS2019（Debug x86）

功能：获取当前线程内ebp与函数返回值

结果：

 代码示例：

#include <iostream>
#include <list>
using namespace std;

typedef struct
{
    void* prev_ebp;
    void* call_ret;
} context;

__declspec(naked) void* get_ebp(void)
{
    __asm
    {
        mov eax, ebp
        ret
    }
}
typedef list<context> pcontext;
list<context>::iterator itor;
pcontext get_context()
{
    pcontext pstack;
    context tmpstack;26     tmpstack.prev_ebp = get_ebp();
    tmpstack.call_ret = *(void**)((char*)tmpstack.prev_ebp + 4);
    pstack.push_back(tmpstack);
    while (tmpstack.call_ret != 0)
    {
        tmpstack.prev_ebp = *(void**)(tmpstack.prev_ebp);
        tmpstack.call_ret = *(void**)((char*)tmpstack.prev_ebp + 4);
        pstack.push_back(tmpstack);
    }
    return pstack;
}

int main(int argc, char* argv[])
{
    pcontext tmppcontext;
    tmppcontext = get_context();
    for (itor = tmppcontext.begin(); itor != tmppcontext.end(); itor++)
    {
        cout << "ebp: " << (*itor).prev_ebp << "	ret =" << (*itor).call_ret << endl;
    }
    return 0;
}
