Understanding the purpose of dup/dup2

I'm having difficulty understanding the purposes of using dup/dup2 when involving forks. for example, if we call fork() once, that is, we are creating a child process. In what cases would we need to use dup or dup2 to duplicate the file descriptors for standard output and standard error? What...

What this code should do is: there are parent.cpp and child.cpp. Parent will send whatever is in the buffer to child and child will send back whatever received to parent. I do not know what I am doing wrong. I am confused what is missing in the parent and what else I should include into the child....

POLICY-TEST(8)						User Contributed Perl Documentation					    POLICY-TEST(8)

NAME

       policy-test - Postfix Policy Daemon Testing Tool

SYNOPSIS

       policy-test [options...] unix:/file/path policy-test [options...] inet:hostname:port

	-h, --help		display this help and exit
	    --version		output version information and exit
	-v, --verbose		increase verbosity level

DESCRIPTION

       policy-test is a script that converts Postfix log entries on the standard input into requests to the Postfix policy daemon given as the
       first argument. It can be used for:

       Testing the performance of a policy daemon
       Pre-seeding a Greylist policy daemon with data from the logs

       Note that this program is still in its very early stages of development and does only support a small subset of the normal attributes used
       in the Postfix policy delegation protocol. It basically supports the bare minimum to make it work with Postgrey.

       Also note that a non-standard attribute is being generated: policy_test_time contains the Unix timestamp of when the client connected.
