Reidrect stderr of child process

I have inherited the maintenance of a client app and the associated server.
Simply, the server waits for the client to trigger it; when triggered, the
server runs a child proces, and sends output back to the client.
I an having trouble re-directiong the output from the server to the client.
I found this in the server code:
// The steps for redirecting child process's STDERR:
// 1. Save current STDERR, to be restored later.
// 2. Create anonymous pipe to be STDERR for child process.
// 3. Set STDERR of the parent to be the read handle to the
// pipe, so it is inherited by the child process.
// 4. Create a noninheritable duplicate of the write handle,
// and close the inheritable write handle.
Does that make sense? Is it true for stdout as well as stderr?
When the client triggers the server, it looks like stdout is re-directed,
but not stderr.
Thanks for any help.
