991# Usage: unpack_pdv [file to unpack] [size of off_t]
992# - you have to specify the off_t size ... i have no idea how to extract that

994# the size of the off_t type (in bytes) on the machine that built the pdv
995# archive. one way to determine this is by running the following commands:
996# strings <pdv archive> | grep lseek
997# strace -elseek <pdv archive>
998# basically look for the first lseek command (we do the strings/grep because
999# sometimes the function call is _llseek or something) and steal the 2nd
1000# parameter. here is an example:
1001# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1002# lseek
1003# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1004# lseek(3, -4, SEEK_END) = 2981250
