从C ++中的DLL捕获调试信息 [英] Capture debug information from a dll in C++

问题描述

我正在运行一个使用C ++ dll的exe，该dll输出调试信息.我可以在Visual Studio的输出窗口中查看输出信息.您能否提出一些示例，这些示例在C ++中实现侦听器，这些侦听器可以拦截此信息并将其保存到日志文件或缓冲区中.我不希望所有调试数据(例如exe已加载/卸载)，而只希望从此dll输出的数据.

I am running an exe which makes use of a C++ dll and the dll outputs debug information. I can view the output info in the output window of Visual Studio. Can you suggest samples which implement listeners in C++ which can intercept this information and save it to a log file or a buffer. I do not want all the debugging data (for example exe has loaded/unloaded) but only the data that is output from this dll. Is there a way of doing it?

推荐答案

此处有一篇文章向您展示如何捕获对OutputDebugString的调用:

OutputDebugString的机制 [

Here''s an article that show you how to capture calls to OutputDebugString:

Mechanism of OutputDebugString[^]

Assuming that''s what the DLL is calling, you should be able to make that code work for your purposes.
