923# Unpack those pesky pdv generated files ...
924# They're self-unpacking programs with the binary package stuffed in
925# the middle of the archive. Valve seems to use it a lot ... too bad
926# it seems to like to segfault a lot :(. So lets take it apart ourselves.
927#
928# Usage: unpack_pdv [file to unpack] [size of off_t]
929# - you have to specify the off_t size ... i have no idea how to extract that
930# information out of the binary executable myself. basically you pass in
931# the size of the off_t type (in bytes) on the machine that built the pdv
932# archive. one way to determine this is by running the following commands:
933# strings <pdv archive> | grep lseek
934# strace -elseek <pdv archive>
935# basically look for the first lseek command (we do the strings/grep because
936# sometimes the function call is _llseek or something) and steal the 2nd
937# parameter. here is an example:
938# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
939# lseek
940# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
941# lseek(3, -4, SEEK_END) = 2981250
942# thus we would pass in the value of '4' as the second parameter.
