8# @BLURB: many extra (but common) functions that are used in ebuilds
9# @DESCRIPTION:
10# The eutils eclass contains a suite of functions that complement
11# the ones that ebuild.sh already contain. The idea is that the functions
12# are not required in all ebuilds but enough utilize them to have a common
13# home rather than having multiple ebuilds implementing the same thing.
14#
15# Due to the nature of this eclass, some functions may have maintainers
16# different from the overall eclass!

1115# the middle of the archive. Valve seems to use it a lot ... too bad
1116# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1117#
1118# You have to specify the off_t size ... I have no idea how to extract that
1119# information out of the binary executable myself. Basically you pass in
1120# the size of the off_t type (in bytes) on the machine that built the pdv

1122#
1123# One way to determine this is by running the following commands:

1126# strings <pdv archive> | grep lseek
1127# strace -elseek <pdv archive>
1128# @CODE

1130# Basically look for the first lseek command (we do the strings/grep because
1131# sometimes the function call is _llseek or something) and steal the 2nd
1132# parameter. Here is an example:
1133#
1134# @CODE
1135# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1136# lseek
1137# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1138# lseek(3, -4, SEEK_END) = 2981250
1139# @CODE
