804# the size of the off_t type (in bytes) on the machine that built the pdv
805# archive. one way to determine this is by running the following commands:
806# strings <pdv archive> | grep lseek
807# strace -elseek <pdv archive>
808# basically look for the first lseek command (we do the strings/grep because
809# sometimes the function call is _llseek or something) and steal the 2nd
810# parameter. here is an example:
811# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
812# lseek
813# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
814# lseek(3, -4, SEEK_END) = 2981250
815# thus we would pass in the value of '4' as the second parameter.
