1074# strings <pdv archive> | grep lseek
1075# strace -elseek <pdv archive>
1076# basically look for the first lseek command (we do the strings/grep because
1077# sometimes the function call is _llseek or something) and steal the 2nd
1078# parameter. here is an example:
1079# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1080# lseek
1081# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
