1085# strings <pdv archive> | grep lseek
1086# strace -elseek <pdv archive>
1087# basically look for the first lseek command (we do the strings/grep because
1088# sometimes the function call is _llseek or something) and steal the 2nd
1089# parameter. here is an example:
1090# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1091# lseek
1092# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1093# lseek(3, -4, SEEK_END) = 2981250
