XTD(ADM)                                   UNIX System V



     Name
          xtd - extract and print xt driver link structure


     Syntax
          xtd [-f] [-n ...]


     Description
          The xtd command is a debugging tool for the  xt(HW)  driver.
          It performs an XTIOCDATA ioctl(S) call on its standard input
          file to extract the link data  structure  for  the  attached
          group  of  channels.  This call will fail if data extraction
          has not been configured in the driver or the standard  input
          is  not attached to an xt(HW) channel.  The data are printed
          one item per line on the standard output.  The output should
          probably be formatted via pr -3.

          The optional flags affect output as follows:

            -n      n is a number in the range 0 to 7.  Channel  n  is
                    included  in  the  list of channels to be printed.
                    The  default  prints  all  channels,  whereas  the
                    occurrence  of one or more channel numbers implies
                    a subset.

            -f      Causes a ``formfeed'' character to be put  out  at
                    the  end  of  the  output for the benefit of page-
                    display programs.


     Diagnostics
          Returns 0 upon successful completion; 1 otherwise.
