Simple access to UNIX domain sockets.
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 connections are 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.
