801# information out of the binary executable myself. basically you pass in
802# the size of the off_t type (in bytes) on the machine that built the pdv
803# archive. one way to determine this is by running the following commands:
804# strings <pdv archive> | grep lseek
805# strace -elseek <pdv archive>
806# basically look for the first lseek command (we do the strings/grep because
807# sometimes the function call is _llseek or something) and steal the 2nd
808# parameter. here is an example:
809# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
810# lseek
811# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
812# lseek(3, -4, SEEK_END) = 2981250
813# thus we would pass in the value of '4' as the second parameter.
