800# archive. one way to determine this is by running the following commands:
801# strings <pdv archive> | grep lseek

803# basically look for the first lseek command (we do the strings/grep because
804# sometimes the function call is _llseek or something) and steal the 2nd
805# parameter. here is an example:
806# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
807# lseek
808# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
809# lseek(3, -4, SEEK_END) = 2981250
810# thus we would pass in the value of '4' as the second parameter.
