xtd(ADM)
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
xtd
channel.
The data is 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.
Exit values
Returns 0 upon successful completion; 1 otherwise.
