How does inetd transfer control to respective services?

How does inetd transfer control to the service, Below is my understanding * inetd listens on every port mentioned in /etc/inetd.conf * If a client make a request to one of the port that inetd listens then inetd transfers control of that request to a service by spinning it as a child process by looking /etc/inetd.conf * It is acts as multiplexer. My doubt is below * How the request is handover to the child process (respective service daemon)? * Already connection is made on the port by inetd so child process can't that port again until the inetd releases that port. If inetd releases that port then existing client connection will be droped (kindly correct me if my understanding is wrong).
