kdump
displays the kernel trace files
produced with ktrace(1) in
human readable format. The file ktrace.out in the
current directory is displayed, unless either the -f
option is used, or a file name is supplied as the last argument.
The options are as follows:
-d
-E

emulation-f
file-l

kdump
tries
to decode many system calls into a more human readable format. For
example, ioctl(2) values are
replaced with the macro name and errno values are
replaced with the
strerror(3) string.
Suppressing this feature yields a more consistent output format and is
easily amenable to further processing.-p
