config EGLIBC_OPTION_EGLIBC_ADVANCED_INET6
bool "IPv6 Advanced Sockets API support (RFC3542)"
default y
select EGLIBC_OPTION_EGLIBC_INET
help
This option group includes the functions specified by RFC 3542,
"Advanced Sockets Application Program Interface (API) for
IPv6".
This option group includes the following functions:

bool "Functions for producing backtraces"
default y
help
This option group includes functions for producing a list of
the function calls that are currently active in a thread, from
within the thread itself. These functions are often used
within signal handlers, to produce diagnostic output.
This option group includes the following functions:
backtrace
backtrace_symbols
backtrace_symbols_fd
config EGLIBC_OPTION_EGLIBC_BSD
bool "BSD-specific functions, and their compatibility stubs"
default y
help
This option group includes functions specific to BSD kernels.
A number of these functions have stub versions that are also
included in libraries built for non-BSD systems for
compatibility.
This option group includes the following functions:

config EGLIBC_OPTION_EGLIBC_CXX_TESTS
bool "Tests that link against the standard C++ library."
default y
select EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
select EGLIBC_OPTION_EGLIBC_LIBM
help
This option group does not include any C library functions;
instead, it controls which EGLIBC tests an ordinary 'make
tests' runs. With this group disabled, tests that would
normally link against the standard C++ library are not
run.
The standard C++ library depends on the math library 'libm' and
the wide character I/O functions included in EGLIBC. If those
option groups are disabled, this test must also be disabled.
config EGLIBC_OPTION_EGLIBC_CATGETS
bool "Functions for accessing message catalogs"
default y
select EGLIBC_OPTION_EGLIBC_LOCALE_CODE
help
This option group includes functions for accessing message
catalogs: catopen, catclose, and catgets.
This option group depends on the EGLIBC_LOCALE_CODE
option group; if you disable that, you must also disable this.
config EGLIBC_OPTION_EGLIBC_CHARSETS
bool "iconv/gconv character set conversion libraries"
default y
help
This option group includes support for character sets other
than ASCII (ANSI_X3.4-1968) and Unicode and ISO-10646 in their
various encodings. This affects both the character sets
supported by the wide and multibyte character functions, and
those supported by the 'iconv' functions.
With this option group disabled, EGLIBC supports only the
following character sets:
ANSI_X3.4 - ASCII

help
This option group includes functions for looking up mail
aliases in '/etc/aliases' or using nsswitch. It includes the
following functions:
endaliasent
getaliasbyname
getaliasbyname_r
getaliasent
getaliasent_r
setaliasent
When this option group is disabled, the NSS service libraries
also lack support for querying their mail alias tables.
config EGLIBC_OPTION_EGLIBC_ENVZ
bool "Functions for handling envz-style environment vectors."
default y
help
This option group contains functions for creating and operating
on envz vectors. An "envz vector" is a vector of strings in a
contiguous block of memory, where each element is a name-value
pair, and elements are separated from their neighbors by null
characters.
This option group includes the following functions:
envz_add envz_merge
envz_entry envz_remove
envz_get envz_strip
config EGLIBC_OPTION_EGLIBC_FCVT
bool "Functions for converting floating-point numbers to strings"

help
This option group includes the following functions:
addseverity fmtmsg
config EGLIBC_OPTION_EGLIBC_FSTAB
bool "Access functions for 'fstab'"
default y
help
This option group includes functions for reading the mount
point specification table, '/etc/fstab'. These functions are
not included in the POSIX standard, which provides the
'getmntent' family of functions instead.
This option group includes the following functions:
endfsent getfsspec
getfsent setfsent
getfsfile
config OPTION_EGLIBC_FTRAVERSE
bool "Functions for traversing file hierarchies"

config EGLIBC_OPTION_EGLIBC_GETLOGIN
bool "The getlogin function"
default y
select EGLIBC_OPTION_EGLIBC_UTMP
help
This function group includes the 'getlogin' and 'getlogin_r'
functions, which return the user name associated by the login
activity with the current process's controlling terminal.
With this option group disabled, the 'glob' function will not
fall back on 'getlogin' to find the user's login name for tilde
expansion when the 'HOME' environment variable is not set.
config EGLIBC_OPTION_EGLIBC_INET
bool "Networking support"
default y
help
This option group includes networking-specific functions and
data. With EGLIBC_INET disabled, the EGLIBC
installation and API changes as follows:
- The following libraries are not installed:
libanl
libnsl

- The rpcgen, nscd, and rpcinfo commands are not installed.
- The 'rpc' file (a text file listing RPC services) is not installed.
Socket-related system calls do not fall in this option group,
because many are also used for other inter-process
communication mechanisms. For example, the 'syslog' routines
use Unix-domain sockets to communicate with the syslog daemon;
syslog is valuable in non-networked contexts.
config EGLIBC_OPTION_EGLIBC_LIBM
bool "libm (math library)"
default y
help
This option group includes the 'libm' library, containing
mathematical functions. If this option group is omitted, then
an EGLIBC installation does not include shared or unshared versions
of the math library.
Note that this does not remove all floating-point related
functionality from EGLIBC; for example, 'printf' and 'scanf'
can still print and read floating-point values with this option
group disabled.
Note that the ISO Standard C++ library 'libstdc++' depends on
EGLIBC's math library 'libm'. If you disable this option
group, you will not be able to build 'libstdc++' against the
resulting EGLIBC installation.
config EGLIBC_OPTION_EGLIBC_LOCALES
bool "Locale definitions"
default y
help
This option group includes all locale definitions other than
that for the "C" locale. If this option group is omitted, then
only the "C" locale is supported.
config EGLIBC_OPTION_EGLIBC_LOCALE_CODE
bool "Locale functions"
default y
select EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR if EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10
help
This option group includes locale support functions, programs,
and libraries. With EGLIBC_LOCALE_FUNCTIONS disabled,
EGLIBC supports only the 'C' locale (also known as 'POSIX'),
and ignores the settings of the 'LANG' and 'LC_*' environment
variables.
With EGLIBC_LOCALE_CODE disabled, the following
functions are omitted from libc:
duplocale localeconv nl_langinfo rpmatch strfmon_l
freelocale newlocale nl_langinfo_l strfmon uselocale
Furthermore, only the LC_CTYPE and LC_TIME categories of the
standard "C" locale are available.
The EGLIBC_CATGETS option group depends on this option
group; if you disable EGLIBC_LOCALE_CODE, you must also
disable EGLIBC_CATGETS.
config EGLIBC_OPTION_EGLIBC_NIS
bool "Support for NIS, NIS+, and the special 'compat' services."
default y
select EGLIBC_OPTION_EGLIBC_INET
select EGLIBC_OPTION_EGLIBC_SUNRPC
help
This option group includes the NIS, NIS+, and 'compat' Name
Service Switch service libraries. When it is disabled, those
services libraries are not installed; you should remove any
references to them from your 'nsswitch.conf' file.
This option group depends on the EGLIBC_INET option
group; you must enable that to enable this option group.
config EGLIBC_OPTION_EGLIBC_NSSWITCH
bool "Name service switch (nsswitch) support"
default y
help
This option group includes support for the 'nsswitch' facility.
With this option group enabled, all EGLIBC functions for
accessing various system databases (passwords and groups;
networking; aliases; public keys; and so on) consult the
'/etc/nsswitch.conf' configuration file to decide how to handle
queries.
With this option group disabled, EGLIBC uses a fixed list of
services to satisfy queries on each database, as requested by
configuration files specified when EGLIBC is built. Your
'option-groups.config' file must set the following two
variables:
EGLIBC_NSSWITCH_FIXED_CONFIG
Set this to the name of a file whose contents observe the
same syntax as an ordinary '/etc/nsswitch.conf' file. The
EGLIBC build process parses this file just as EGLIBC would
at run time if EGLIBC_NSSWITCH were enabled, and
produces a C library that uses the nsswitch service
libraries to search for database entries as this file
specifies, instead of consulting '/etc/nsswitch.conf' at run
time.
This should be an absolute filename. The EGLIBC build
process may use it from several different working
directories. It may include references to Makefile
variables like 'common-objpfx' (the top of the build tree,
with a trailing slash), or '..' (the top of the source tree,
with a trailing slash).
The EGLIBC source tree includes a sample configuration file
named 'nss/fixed-nsswitch.conf'; for simple configurations,
you will probably want to delete references to databases not
needed on your system.
EGLIBC_NSSWITCH_FIXED_FUNCTIONS
The EGLIBC build process uses this file to decide which
functions to make available from which service libraries.
The file 'nss/fixed-nsswitch.functions' serves as a sample
configuration file for this setting, and explains its syntax
and meaning in more detail.
This should be an absolute file name. The EGLIBC build
process may use it from several different working
directories. It may include references to Makefile
variables like 'common-objpfx' (the top of the build tree,
with a trailing slash), or '..' (the top of the source tree,
with a trailing slash).
Be sure to mention each function in each service you wish to
use. If you do not mention a service's function here, the
EGLIBC database access functions will not find it, even if
it is listed in the EGLIBC_NSSWITCH_FIXED_CONFIG
file.
In this arrangement, EGLIBC will not use the 'dlopen' and
'dlsym' functions to find database access functions. Instead,
libc hard-codes references to the service libraries' database
access functions. You must explicitly link your program
against the name service libraries (those whose names start
with 'libnss_', in the sysroot's '/lib' directory) whose
functions you intend to use. This arrangement helps
system-wide static analysis tools decide which functions a
system actually uses.
Note that some nsswitch service libraries require other option
groups to be enabled; for example, the EGLIBC_INET
option group must be enabled to use the 'libnss_dns.so.2'
service library, which uses the Domain Name System network
protocol to answer queries.
config EGLIBC_OPTION_EGLIBC_RCMD
bool "Support for 'rcmd' and related library functions"
default y
select EGLIBC_OPTION_EGLIBC_INET
help
This option group includes functions for running commands on
remote machines via the 'rsh' protocol, and doing authentication
related to those functions. This also includes functions that
use the 'rexec' protocol.
This option group includes the following functions:
rcmd ruserok
rcmd_af ruserok_af
rexec iruserok
rexec_af iruserok_af
rresvport ruserpass
rresvport_af
config EGLIBC_OPTION_EGLIBC_SPAWN
bool "Support for POSIX posix_spawn functions"
default y
help
This option group includes the POSIX functions for executing
programs in child processes without using 'fork' or 'vfork'.
This option group includes the following functions:
posix_spawn
posix_spawnattr_destroy
posix_spawnattr_getflags
posix_spawnattr_getpgroup
posix_spawnattr_getschedparam
posix_spawnattr_getschedpolicy
posix_spawnattr_getsigdefault

posix_spawn_file_actions_addopen
posix_spawn_file_actions_destroy
posix_spawn_file_actions_init
posix_spawnp
This option group also provides the ability for the iconv,
localedef, and locale programs to operate transparently on
compressed charset definitions. When this option group is
disabled, those programs will only operate on uncompressed
charmap files.
config EGLIBC_OPTION_EGLIBC_STREAMS
bool "Support for accessing STREAMS."
default y
help
This option group includes functions for reading and writing
messages to and from STREAMS. The STREAMS interface provides a
uniform mechanism for implementing networking services and other
character-based I/O. (STREAMS are not to be confused with
<stdio.h> FILE objects, also called 'streams'.)
This option group includes the following functions:
getmsg putpmsg
getpmsg fattach
isastream fdetach
putmsg
config EGLIBC_OPTION_EGLIBC_SUNRPC
bool "Support for the Sun 'RPC' protocol."
default y
select EGLIBC_OPTION_EGLIBC_INET
help
This option group includes support for the Sun RPC protocols,
including the 'rpcgen' and 'rpcinfo' programs.
config EGLIBC_OPTION_EGLIBC_UTMP
bool "Older access functions for 'utmp' login records"
default y
help
This option group includes the older 'utent' family of
functions for accessing user login records in the 'utmp' file.
POSIX omits these functions in favor of the 'utxent' family,
and they are obsolete on systems other than Linux.
This option group includes the following functions:
endutent
getutent
getutent_r
getutid
getutid_r
getutline
getutline_r
logwtmp
pututline
setutent
updwtmp

libutil.so (and libutil.a)
config EGLIBC_OPTION_EGLIBC_UTMPX
bool "POSIX access functions for 'utmp' login records"
default y
select EGLIBC_OPTION_EGLIBC_UTMP
help
This option group includes the POSIX functions for reading and
writing user login records in the 'utmp' file (usually
'/var/run/utmp'). The POSIX functions operate on 'struct
utmpx' structures, as opposed to the family of older 'utent'
functions, which operate on 'struct utmp' structures.
This option group includes the following functions:
endutxent
getutmp
getutmpx
getutxent
getutxid
getutxline
pututxline
setutxent
updwtmpx
utmpxname
config EGLIBC_OPTION_EGLIBC_WORDEXP

help
This option group includes the 'wordexp' function for
performing word expansion in the manner of the shell, and the
accompanying 'wordfree' function.
config EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR
bool "ISO C library wide character functions, excluding I/O"
default y
depends EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10
help
This option group includes the functions defined by the ISO C
standard for working with wide and multibyte characters in
memory. Functions for reading and writing wide and multibyte
characters from and to files call in the
POSIX_WIDE_CHAR_DEVICE_IO option group.
This option group includes the following functions:
btowc mbsinit wcscspn wcstoll
iswalnum mbsrtowcs wcsftime wcstombs
iswalpha mbstowcs wcslen wcstoul
iswblank mbtowc wcsncat wcstoull

config EGLIBC_OPTION_POSIX_REGEXP
bool "Regular expressions"
default y
help
This option group includes the POSIX regular expression
functions, and the associated non-POSIX extensions and
compatibility functions.
With POSIX_REGEXP disabled, the following functions are
omitted from libc:
re_comp re_max_failures regcomp
re_compile_fastmap re_search regerror
re_compile_pattern re_search_2 regexec
re_exec re_set_registers regfree
re_match re_set_syntax rpmatch
re_match_2 re_syntax_options
Furthermore, the compatibility regexp interface defined in the
<regexp.h> header file, 'compile', 'step', and 'advance', is
omitted.
config EGLIBC_OPTION_POSIX_REGEXP_GLIBC
bool "Regular expressions from GLIBC"
default y
select EGLIBC_OPTION_POSIX_REGEXP
depends EGLIBC_VERSION_2_10
help
This option group specifies which regular expression
library to use. The choice is between regex
implementation from GLIBC and regex implementation from
libiberty. The GLIBC variant is fully POSIX conformant and
optimized for speed; regex from libiberty is more than twice
as small while still is enough for most practical purposes.
config EGLIBC_OPTION_POSIX_WIDE_CHAR_DEVICE_IO
bool "Input and output functions for wide characters"
default y
select EGLIBC_OPTION_POSIX_C_LANG_WIDE_CHAR if EGLIBC_VERSION_2_8 || EGLIBC_VERSION_2_9 || EGLIBC_VERSION_2_10
help
This option group includes functions for reading and writing
wide characters to and from <stdio.h> streams.
This option group includes the following functions:
fgetwc fwprintf putwchar vwscanf
fgetws fwscanf ungetwc wprintf
fputwc getwc vfwprintf wscanf
fputws getwchar vfwscanf
fwide putwc vwprintf
This option group further includes the following unlocked
variants of the above functions:
fgetwc_unlocked getwc_unlocked
fgetws_unlocked getwchar_unlocked
fputwc_unlocked putwc_unlocked
fputws_unlocked putwchar_unlocked
Note that the GNU standard C++ library, 'libstdc++.so', uses
some of these functions; you will not be able to link or run
C++ programs if you disable this option group.
This option group also affects the behavior of the following
functions:
fdopen
fopen
fopen64
freopen
freopen64
These functions all take an OPENTYPE parameter which may
contain a string of the form ",ccs=CHARSET", indicating that
the underlying file uses the character set named CHARSET.
This produces a wide-oriented stream, which is only useful
when the functions included in this option group are present.
If the user attempts to open a file specifying a character set
in the OPENTYPE parameter, and EGLIBC was built with this
option group disabled, the function returns NULL, and sets
errno to EINVAL.
