From: Mark Weiser <mark.umcp-cs@UDel-Relay> Date: 28 Mar 1983 0340-PST Just fork off the child with a pipe connected to standard input, and the other end of the pipe under the control of the parent. Use dup2() to move the pipe file descripter to 0 (which is standard in) after the fork but before the exec. Make sure to close all unused descripters in each process to make things clean.
