XTD(lM) XTD(lM)
NAME
xtd - extract and print xt driver link structure
SYNOPSIS
xtd [-f] [-n ... ]
DESCRIPTION
The xtd command is a debugging tool for the xt(7) driver. It performs an
XTIOCDATA ioctl(2) 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(7) 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 chan ­
nels, 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.
EXIT STATUS
Returns 0 upon successful completion, 1 otherwise.
