是否可以将标准输出从Visual Studio重定向到输出窗口?

Is it possible to redirect standard output to the output window from Visual Studio?

我在程序中使用了OutputDebugString，但是我使用了一些带有带有printf或cout的输出调试消息的库.

I use OutputDebugString in my program, but I use some libraries that have output debug messages with printf's or cout's.

推荐答案

直接标准输出重定向将不起作用，因为没有对应于OutputDebugString的句柄.但是，应该有一种方法:

Straightforward standard output redirection will not work, as there is no handle corresponding to OutputDebugString. However, there should be a way:

可以通过以下方式完成:将标准输出重定向到管道，然后创建一个线程，该线程将读取该管道并使用OutputDebugString打印从该管道读取的任何内容.

It could be done by redirecting standard output to a pipe, and then creating a thread which would read the pipe and print anything read from it using OutputDebugString.

注意:我很久以前就打算实现此功能，因为我面临的问题与您完全相同(某些库使用printf或fprintf(stderr ....).但是，我从未真正做到过.我总是结束对库的修改，因此我没有可行的实现，但我认为从原理上讲应该是可行的.

Note: I was contemplating for a long ago to implement this, as I am facing exactly the same problem as you do (some libraries using printf or fprintf(stderr....). However, I never really did this. I have always ended modifying the libraries instead, and therefore I do not have a working implementation, but I think it should be feasible in principle.
