46# This function simply returns the desired lib directory. With portage
47# 2.0.51, we now have support for installing libraries to lib32/lib64
48# to accomidate the needs of multilib systems. It's no longer a good idea
49# to assume all libraries will end up in lib. Replace any (sane) instances
50# where lib is named directly with $(get_libdir) if possible.

1080# Usage: unpack_pdv [file to unpack] [size of off_t]
1081# - you have to specify the off_t size ... i have no idea how to extract that

1083# the size of the off_t type (in bytes) on the machine that built the pdv
1084# archive. one way to determine this is by running the following commands:
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
