Communicating with a background process

[Bruce A. Kern]

The system calls which will accomplish what you want are pipe(2) and
dup(2).  Two calls to pipe are required, one to open a read channel
and one for a write channel.  The dup calls allow the file descriptors
to be remapped onto 0 and 1 ( standard i/o ).  See Rochkind's excellent
book "Advanced Unix Programming" for details on this procedure.  If 
you need further examples contact me via E-mail.
