Correct answer. You actually need a couple of pipes between the parent
and the child process. The child connects the pipes to stdout and stderr
before it exec()s a new process. For some exmple code, have a look at
the DOSemu source (available at http://www.dosemu.org/), file
src/base/misc/dos2linux.c, function run_unix_command().
