inetd doesn't work that way. It doesn't "turn ports off", it either listens or doesn't listen on a particular port and runs a certain service when someone connects according to a text file. If you insisted in doing it in C, you'd probably be calling shell scripts with system() to edit inetd.conf then signalling inetd to reload its config file.

In other words it's not a system function you're asking for, this isn't a firewall; you have to ask inetd to do something. You could listen yourself, but then you'd be writing your own inetd from scratch instead of controlling the one that already exists.

NAME

       rdate - set system date from a remote host

SYNOPSIS

       rdate hostname
