Presumably you are using dup() or dup2() to map the child's stdout to
your pipe.  You can do another dup2 to map stderr to the same pipe.
Alternatively, you can open a separate pipe to handle the stderr.  If
you use 2 pipes, you can use select() or XtAppAddInput() on the parent
side to manage them.
