Redirecting stdout of CreateProcess() to a pipe and reading it in another process c++ windows

Question

I have a main c++ program. This program at its startup launches another process executable using CreateProcess() function. Now I want to redirect the standard output (stdout) of this new process to the main c++ program. For this purpose I would like to use a pipe in windows. I am able to achieve this in linux using fork() and pipe (), but I am unable to get CreatePipe() working on windows. The pipe is created but I am unable to get any data.

Can someone please provide me some example or sample code for this purpose ? I have successfully redirected the stdout of CreateProcess to a file but the pipe does not work.

Thanks in advance.

also put up some of ur code. What did u do for working through windows. — Sameer Sawla, Mar 11 '15 at 18:42
