tcp-listen TCPPORT #!optional BACKLOG HOSTprocedure

Creates and returns a TCP listener object that listens for connections on TCPPORT, which should be an exact integer. BACKLOG specifies the number of maximally pending connections (and defaults to 100). If the optional argument HOST is given and not #f, then only incoming connections for the given host (or IP) are accepted.
