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!

1087# They're self-unpacking programs with the binary package stuffed in
1088# the middle of the archive. Valve seems to use it a lot ... too bad
1089# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1090#
1091# You have to specify the off_t size ... I have no idea how to extract that
1092# information out of the binary executable myself. Basically you pass in
1093# the size of the off_t type (in bytes) on the machine that built the pdv
1094# archive.
1095#
1096# One way to determine this is by running the following commands:

1099# strings <pdv archive> | grep lseek
1100# strace -elseek <pdv archive>
1101# @CODE

1103# Basically look for the first lseek command (we do the strings/grep because
1104# sometimes the function call is _llseek or something) and steal the 2nd
1105# parameter. Here is an example:
1106#
1107# @CODE
1108# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1109# lseek
1110# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1111# lseek(3, -4, SEEK_END) = 2981250
1112# @CODE

1340# the whole 'non-interactive' policy, but damnit I want CD support !
1341#
1342# With these cdrom functions we handle all the user interaction and
1343# standardize everything. All you have to do is call cdrom_get_cds()
1344# and when the function returns, you can assume that the cd has been
1345# found at CDROM_ROOT.

1347# The function will attempt to locate a cd based upon a file that is on
1348# the cd. The more files you give this function, the more cds
1349# the cdrom functions will handle.
1350#
1351# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1352# etc... If you want to give the cds better names, then just export
1353# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1354# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1355# also use the CDROM_NAME_SET bash array.
