1005# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1006#
1007# Usage: unpack_pdv [file to unpack] [size of off_t]
1008# - you have to specify the off_t size ... i have no idea how to extract that
1009# information out of the binary executable myself. basically you pass in
1010# the size of the off_t type (in bytes) on the machine that built the pdv
1011# archive. one way to determine this is by running the following commands:
1012# strings <pdv archive> | grep lseek
1013# strace -elseek <pdv archive>
1014# basically look for the first lseek command (we do the strings/grep because
1015# sometimes the function call is _llseek or something) and steal the 2nd
1016# parameter. here is an example:
1017# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1018# lseek
1019# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1020# lseek(3, -4, SEEK_END) = 2981250
