c++ - 查找被调用函数的线程 ID C++

Question

在 C++3(VS 2008)中:

我想在调用函数时找到被调用函数的线程 ID。我还想看看函数何时调用；它的名称、文件和行。我的例子在这里；

#include "stdafx.h"

#include <iostream>
#include <cstdlib>
#include <process.h>
#include <windows.h>

void test(void *param)
{
    cout << "In thread function" << endl;
    cout << "(" << __FUNCTION__ << ") function in " << __FILE__ << " (line: "     << __LINE__ << ") was called by thread id: " << GetCurrentThreadId() << endl;
    Sleep(1000); // sleep for 1 second
    cout << "Thread function ends" << endl;
    threadFinished = true;
    _endthread();
}

int main()
{
    cout << "Starting thread" << endl;
    cout << "(" << __FUNCTION__ << ") function in " << __FILE__ << "(line: " << __LINE__ << ") was called by thread id: " << GetCurrentThreadId() << endl;
    _beginthread(test,0,NULL);
    while(!threadFinished)
    {
        Sleep(10);
    }
    cout << "Main ends" << endl;
    getchar();
    return 0;
}

这是输出:

Starting thread
(main) function in .\CatchThread.cpp (line: 36) was called by thread id: 8200
In thread function
(test) function in .\CatchThread.cpp (line: 26) was called by thread id: 8860
Thread function ends
Main ends

这按我想要的方式工作。我可以在每个函数中放入包含 GetCurrentThreadId() 的“cout <<...”行，因为这里只有 2 个函数。但是在我的实际产品中有成千上万的功能，不可能将每个功能都放入这个“cout<<...”

我已经为此搜索了两天，并且使用了一个名为 _penter() 的函数。它看起来很有用，因为它在每个被调用的函数之前调用。但是我无法从 _penter();线程 ID、函数名称、行和文件信息。

我想问两件事:

1. 如何在不向每个函数插入“cout<<...”的情况下执行此操作？
2. 如果不可能，我该如何将“cout<<...”添加到我的每个函数中？

任何帮助将不胜感激......

谢谢...

在 C++11/14/17 中它看起来像这样。

#include<thread>
void calledFunction(){

std::cout << \_\_func\_\_ << " called from thread:" << std::this_thread::get_id() << std::endl;

}
