	Assuming something like "foo | bar" doesn't work, the next thing 
that comes to mind for me is "mkfifo", ie:

mkfifo /tmp/foobarfifo
parent > foobarfifo
child < foobarfifo
rm /tmp/foobarfifo

	If you actually need to do this redirection with C code (not 
through bash), then I would suggest looking at the man pages for either 
pipe(2), dup(2) or dup2(2).
