Take a look at this:
http://www.RapidEuphoria.com/iolib.tar.gz

And also this:
http://www.geocities.com/jbrown1050/pipeio_tar_gz.html

The first will let you call the C functions for file IO and half-duplex
pipes.

The second will give you full duplex pipes, but is a lot harder to use.
It however
will let you redirect to a command. This one is built on the libc
function dup2(),
as well as the libc pipe() function.

'man 2 dup2' and 'man 2 pipe' will give you the details.
