32 The COMM Package

This chapter provides reference entries for the functions in the COMM package.

The COMM package provides the TCP/IP interface. TCP/IP sockets can be used to communicate between processes and machines and the mechanism allows LispWorks to connect to or implement a server. It also allows using Secure Sockets Layer (SSL) processing in the socket.

The COMM package also provides the Asynchronous I/O API including UDP sockets as described in 25.8 Asynchronous I/O.

An overview of this functionality is in 25 TCP and UDP socket communication and SSL.

Before the interface can be used the module "comm" must be loaded using:

(require "comm")
