/* These are defined by the user (or the compiler)
|
|
to specify the desired environment:
|
|
|
|
__STRICT_ANSI__ ANSI Standard C.
|
|
_POSIX_SOURCE IEEE Std 1003.1.
|
|
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if ==2 add IEEE Std 1003.2.
|
|
_BSD_SOURCE ANSI, POSIX, and 4.3BSD things.
|
|
_SVID_SOURCE ANSI, 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 ANSI 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_POSIX Define IEEE Std 1003.1 things.
|
|
__USE_POSIX2 Define IEEE Std 1003.2 things.
|
|
__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 macro `__GNU_LIBRARY__' is defined by this file unconditionally.
|
|
|
|
All macros listed above as possibly being defined by this file are
|
|
explicitly undefined if they are not explicitly defined.
|
|
Feature-test macros that are not defined by the user or compiler

but are implied by the other feature-test macros defined (or by the
|
|
lack of any definitions) are defined by the file. */
