unix_sockets - Communicate using unix domain sockets

       Unix domain sockets are a filesystem based IPC mechanism similar to IP sockets, except that they can only
       be used by processes on the same system.  This package provides a wrapper to use them from Tcl scripts.

       unix_sockets::listenpathaccept_handler
              Open  a  listening  socket with the path path.  If path already exists, it is unlinked first.  You
              must have permission to create path in it's parent directory.   When  a  client  connects  to  the
              listening  socket,  accept_handler is invoked with the channel handle of the new client connection
              appended.

       unix_sockets::connectpath
              Connect as a client to the unix domain socket path.  The channel handle  for  the  new  socket  is
              returned.

       A simple server that echos back to the client the first line it sends, then closes the socket:

              procreadable{con}{setmsg[gets$con]puts$con$msgclose$con}procaccept{con}{chanevent$conreadable[listreadable$con]}setlisten[unix_sockets::listen/tmp/example.socketaccept]vwait::forever

       A client that opens a socket, writes a line to it, waits for a response and exits:

              procreadable{con}{setmsg[gets$con]puts"gotresponse:($msg)"set::done1}setcon[unix_sockets::connect/tmp/example.socket]puts$con"hello,world"flush$conchanevent$conreadable[listreadable$con]vwait::done

       socket, channel, unix, ipc
