How can a parent and child process communicate?
Answer Posted / yogesh warad
Parent and child processes can communicate with unnamed pipe,
but the pipe should be created before creating the
child(i.e. forking).
After forking the process, child process inherits all
properties of parent, hence pipe also. This pipe can ce used
to communicate between parent and child process. But if one
wants to use exec(s), then this technique is not useful. The
user have to use named pipe or Message-Queue.
