Getting the output from a process created by CreateProcess

Question

In my console app I've created a process by using CreateProcess method. Now, this process either writes to the console "OK" or "Not OK". How can I intercept that information so I can as well as to console write it to a file?

Answer 1

• Use CreatePipe to create an anonymous pipe.
• Set the standard output of your child to be the write end of the pipe
• Parent process reads from the read end of the pipe
• Parent process can write to file and console, and wherever.

See Creating a Child Process with Redirected Input and Output on MSDN for full details.
