789# Usage: unpack_pdv [file to unpack] [size of off_t]
790# - you have to specify the off_t size ... i have no idea how to extract that
791# information out of the binary executable myself. basically you pass in
792# the size of the off_t type (in bytes) on the machine that built the pdv
793# archive. one way to determine this is by running the following commands:
794# strings <pdv archive> | grep lseek
795# strace -elseek <pdv archive>
796# basically look for the first lseek command (we do the strings/grep because
797# sometimes the function call is _llseek or something) and steal the 2nd
798# parameter. here is an example:
799# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
800# lseek
