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!

1090# the middle of the archive. Valve seems to use it a lot ... too bad
1091# it seems to like to segfault a lot :(. So lets take it apart ourselves.
1092#
1093# You have to specify the off_t size ... I have no idea how to extract that
1094# information out of the binary executable myself. Basically you pass in
1095# the size of the off_t type (in bytes) on the machine that built the pdv
1096# archive.
1097#
1098# One way to determine this is by running the following commands:

1101# strings <pdv archive> | grep lseek
1102# strace -elseek <pdv archive>
1103# @CODE

1105# Basically look for the first lseek command (we do the strings/grep because
1106# sometimes the function call is _llseek or something) and steal the 2nd
1107# parameter. Here is an example:
1108#
1109# @CODE
1110# vapier@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
1111# lseek
1112# vapier@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
1113# lseek(3, -4, SEEK_END) = 2981250
1114# @CODE

1344# With these cdrom functions we handle all the user interaction and

1350# the cd. The more files you give this function, the more cds
1351# the cdrom functions will handle.

1354# etc... If you want to give the cds better names, then just export
1355# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
