筛选C ++ / Win32命令行输出消息

Question

I have a Win32/C++ Command line program which displays message using "printf()" function. The program uses a 3rd party lib/dll which generates log message to the same console screen.

So is there a way to redirect all output messages to a PLACE and filter my own message to the console screen?

Answer 1

There are 3 main 'streams' that console application may have:

1. Standard output
2. Error output
3. Log output

More info here

Now you can redirect one/all/multiple outputs to file, or any other stream like here

Then when you have file you can read and then filter to way that you like to see.
