/* These are defined by the user (or the compiler)

to specify the desired environment:
|
|
|
|
__STRICT_ANSI__ ISO Standard C.
|
|
_ISOC9X_SOURCE Extensions to ISO C 89 from ISO C 9x.
|
|
_POSIX_SOURCE IEEE Std 1003.1.
|
|
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
|
|
if >=199309L, add IEEE Std 1003.1b-1993
|
|
_XOPEN_SOURCE Includes POSIX and XPG things. Set to 500 if
|
|
Single Unix conformance is wanted.
|
|
_XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
|
|
_LARGEFILE_SOURCE Some more functions for correct standard I/O.
|
|
_LARGEFILE64_SOURCE Additional functionality from LFS for large files.
|
|
_FILE_OFFSET_BITS=N Select default filesystem interface.
|
|
_BSD_SOURCE ISO C, POSIX, and 4.3BSD things.
|
|
_SVID_SOURCE ISO C, POSIX, and SVID things.
|
|
_GNU_SOURCE All of the above, plus GNU extensions.
|
|
_REENTRANT Select additionally reentrant object.
|
|
_THREAD_SAFE Same as _REENTRANT, often used by other systems.
|
|
|
|
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
|
|
If none of these are defined, the default is all but _GNU_SOURCE.
|
|
If more than one of these are defined, they accumulate.
|
|
For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
|
|
together give you ISO C, 1003.1, and 1003.2, but nothing else.
|
|
|
|
These are defined by this file and are used by the
|
|
header files to decide what to declare or define:
|
|
|
|
__USE_ISOC9X Define ISO C 9X things.
|
|
__USE_POSIX Define IEEE Std 1003.1 things.
|
|
__USE_POSIX2 Define IEEE Std 1003.2 things.
|
|
__USE_POSIX199309 Define IEEE Std 1003.1b things.
|
|
__USE_XOPEN Define XPG things.
|
|
__USE_XOPEN_EXTENDED Define X/Open Unix things.
|
|
__USE_UNIX98 Define Single Unix V2 things.
|
|
__USE_LARGEFILE64 Define LFS things with separate names.
|
|
__USE_FILE_OFFSET64 Define 64bit interface as default.
|
|
__USE_BSD Define 4.3BSD things.
|
|
__USE_SVID Define SVID things.
|
|
__USE_MISC Define things common to BSD and System V Unix.
|
|
__USE_GNU Define GNU extensions.
|
|
__USE_REENTRANT Define reentrant/thread-safe *_r functions.
|
|
__FAVOR_BSD Favor 4.3BSD things in cases of conflict.

The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are

defined by this file unconditionally. `__GNU_LIBRARY__' is provided

to test for features.

explicitly undefined if they are not explicitly defined.

Feature-test macros that are not defined by the user or compiler
