1008# strings <pdv archive> | grep lseek
1009# strace -elseek <pdv archive>
1010# basically look for the first lseek command (we do the strings/grep because
1011# sometimes the function call is _llseek or something) and steal the 2nd
1012# parameter. here is an example:
1013# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1014# lseek
1015# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
