How do I use pipes to communicate with another proccess that is being run using an execl command?
I know how I can send info to that process but how do I get info back from that proccess?
Some more information on what Im trying to do: I am trying to write a small database program. There are two programs, one program is an interface program where one will write the commands, the other program, the database program, will take in the commands and process them.
the interface program has a parent and a child process. The child is the process that calls the execl and the parent scans for keyboard input
