1040# Usage: unpack_pdv [file to unpack] [size of off_t]
1041# - you have to specify the off_t size ... i have no idea how to extract that
1042# information out of the binary executable myself. basically you pass in
1043# the size of the off_t type (in bytes) on the machine that built the pdv
1044# archive. one way to determine this is by running the following commands:
1045# strings <pdv archive> | grep lseek
1046# strace -elseek <pdv archive>
1047# basically look for the first lseek command (we do the strings/grep because
1048# sometimes the function call is _llseek or something) and steal the 2nd
1049# parameter. here is an example:
1050# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1051# lseek
1052# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1053# lseek(3, -4, SEEK_END) = 2981250
1054# thus we would pass in the value of '4' as the second parameter.
