956#
957# Usage: unpack_pdv [file to unpack] [size of off_t]
958# - you have to specify the off_t size ... i have no idea how to extract that
959# information out of the binary executable myself. basically you pass in
960# the size of the off_t type (in bytes) on the machine that built the pdv
961# archive. one way to determine this is by running the following commands:
962# strings <pdv archive> | grep lseek
963# strace -elseek <pdv archive>
964# basically look for the first lseek command (we do the strings/grep because
965# sometimes the function call is _llseek or something) and steal the 2nd
966# parameter. here is an example:
967# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
968# lseek
969# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
970# lseek(3, -4, SEEK_END) = 2981250
971# thus we would pass in the value of '4' as the second parameter.
