The interface is similar to the builtin TCP socket functionality in CHICKEN.

(procedure) (unix-listen PATHNAME [BACKLOG]): Creates a socket listener object. PATHNAME gives the name of the file that represents the connection. BACKLOG specifies how many pending connectionsare allowed and defaults to 10.
(procedure) (unix-listener? X): Returns #t if X is a unix socket listener object, or #f otherwise.
(procedure) (unix-close LISTENER): Closes the socket associated with the listener object.
(procedure) (unix-accept LISTENER): Waits for a connection from a client and returns two values: an input- and output-port which can be used to communicate with the connecting process. Calling unix-accept does not block other threads from running.
(procedure) (unix-accept-ready? LISTENER): Returns #t if a unix-accept for this listener would not block the current thread, or #f otherwise.
(procedure) (unix-connect PATHNAME): Connects to the socket given in PATHNAME and returns two values: an input- and output-port which allow communication with the server.
(procedure) (unix-listener-fileno LISTENER): Returns the file-descriptor of the socket associated with the given listener object.
(procedure) (unix-listener-path LISTENER): Returns the pathname of the socket associated with the given listener object.
