1015# basically look for the first lseek command (we do the strings/grep because
1016# sometimes the function call is _llseek or something) and steal the 2nd
1017# parameter. here is an example:
1018# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1019# lseek
1020# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
