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!

1058# the middle of the archive. Valve seems to use it a lot ... too bad
1059# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1060#
1061# You have to specify the off_t size ... I have no idea how to extract that

1066# One way to determine this is by running the following commands:
1067# strings <pdv archive> | grep lseek
1068# strace -elseek <pdv archive>
1069# Basically look for the first lseek command (we do the strings/grep because
1070# sometimes the function call is _llseek or something) and steal the 2nd
1071# parameter. Here is an example:
1072# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1073# lseek
1074# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin

1302# the whole 'non-interactive' policy, but damnit I want CD support !
1303#
1304# With these cdrom functions we handle all the user interaction and
1305# standardize everything. All you have to do is call cdrom_get_cds()
1306# and when the function returns, you can assume that the cd has been
1307# found at CDROM_ROOT.

1310# the cd. The more files you give this function, the more cds
1311# the cdrom functions will handle.
1312#
1313# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1314# etc... If you want to give the cds better names, then just export
1315# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1316# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1317# also use the CDROM_NAME_SET bash array.
