CONC(3)                                                   CONC(3)

     NAME
          conc - Datakit concentrator

     SYNOPSIS
          ctlfd = open("rawdkdev/ctl", ORDWR);
          write(ctlfd, "push conc", 9);
          write(ctlfd, "config name nc0 nc1...", n);

          bind -a #Kname /dev

          dkctlfd = open("/dev/name/n/ctl", ORDWR);

     DESCRIPTION
          The concentrator partitions the channel space of a raw
          Datakit device (typically #i or #h) into subspaces of size
          nc0, nc1... Channel numbers are adjusted on all messages so
          that each subdevice sees a channel space starting at zero.
          This arrangement must agree with the switch configuration as
          provisioned by the local Datakit operating company.
