use Unix-domain sockets to communicate with the syslog daemon;
|
|
|
|
|
syslog is valuable in non-networked contexts.

double precision math functions and replaces them with wrappers

EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE
|
|
|

|
|
Libmemusage library buffers the profiling data in memory
|
|
|
|
|
before writing it out to disk. By default, the library
|
|
|
|
|
allocates 1.5M buffer, which can be substantial for some
|
|
|
|
|
systems. EGLIBC_OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE option
|
|
|
|
|
allows to change the default buffer size. It specifies
|
|
|
|
|
the number of entries the buffer should have.
|
|
|
|
|
On most architectures one buffer entry amounts to 48 bytes,
|
|
|
|
|
so setting this option to the value of 512 will reduce the size of
|
|
|
|
|
the memory buffer to 24K.

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_OPTION_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_OPTION_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_OPTION_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
|

|
service library, which uses the Domain Name System network
|
|
|
|
|
protocol to answer queries.

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.
