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!

1134# the middle of the archive. Valve seems to use it a lot ... too bad
1135# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1136#
1137# You have to specify the off_t size ... I have no idea how to extract that
1138# information out of the binary executable myself. Basically you pass in
1139# the size of the off_t type (in bytes) on the machine that built the pdv

1142# One way to determine this is by running the following commands:

1145# strings <pdv archive> | grep lseek
1146# strace -elseek <pdv archive>
1147# @CODE

1149# Basically look for the first lseek command (we do the strings/grep because
1150# sometimes the function call is _llseek or something) and steal the 2nd
1151# parameter. Here is an example:
1152#
1153# @CODE
1154# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1155# lseek
1156# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1157# lseek(3, -4, SEEK_END) = 2981250
1158# @CODE

1715# A temporary hack until portage properly supports DEPENDing on USE
1716# flags being enabled in packages. This will check to see if the specified
1717# DEPEND atom was built with the specified list of USE flags. The
1718# --missing option controls the behavior if called on a package that does
1719# not actually support the defined USE flags (aka listed in IUSE).
1720# The default is to abort (call die). The -a and -o flags control
1721# the requirements of the USE flags. They correspond to "and" and "or"
1722# logic. So the -a flag means all listed USE flags must be enabled
1723# while the -o flag means at least one of the listed IUSE flags must be
1724# enabled. The --hidden option is really for internal use only as it
1725# means the USE flag we're checking is hidden expanded, so it won't be found
1726# in IUSE like normal USE flags.

1728# Remember that this function isn't terribly intelligent so order of optional
1729# flags matter.
