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!

1080# They're self-unpacking programs with the binary package stuffed in
1081# the middle of the archive. Valve seems to use it a lot ... too bad
1082# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1083#
1084# You have to specify the off_t size ... I have no idea how to extract that
1085# information out of the binary executable myself. Basically you pass in
1086# the size of the off_t type (in bytes) on the machine that built the pdv
1087# archive.
1088#
1089# One way to determine this is by running the following commands:
1090#
1091# @CODE
1092# strings <pdv archive> | grep lseek
1093# strace -elseek <pdv archive>
1094# @CODE
1095#
1096# Basically look for the first lseek command (we do the strings/grep because
1097# sometimes the function call is _llseek or something) and steal the 2nd
1098# parameter. Here is an example:
1099#
1100# @CODE
1101# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1102# lseek
1103# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1104# lseek(3, -4, SEEK_END) = 2981250
1105# @CODE
1106#
1107# Thus we would pass in the value of '4' as the second parameter.

1332# Aquire cd(s) for those lovely cd-based emerges. Yes, this violates
1333# the whole 'non-interactive' policy, but damnit I want CD support !
1334#
1335# With these cdrom functions we handle all the user interaction and
1336# standardize everything. All you have to do is call cdrom_get_cds()
1337# and when the function returns, you can assume that the cd has been
1338# found at CDROM_ROOT.
1339#
1340# The function will attempt to locate a cd based upon a file that is on
1341# the cd. The more files you give this function, the more cds
1342# the cdrom functions will handle.
1343#
1344# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1345# etc... If you want to give the cds better names, then just export
1346# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1347# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1348# also use the CDROM_NAME_SET bash array.
