.Dd March 1, 1998
.Dt POSIX.4 9
.Os FreeBSD 3.0
.Sh NAME
.Nm posix4
.Nd "POSIX.4 extensions"
.Sh DESCRIPTION
POSIX.4 adds real time extensions and some commonly used
Berkeley extensions to POSIX.1
This section contains information about the the
POSIX.4 extensions to the system.
.Sh STATUS
March 1, 1998 adds the header file changes to 3.0. There should be no
visible differences as long as _POSIX_VERSION is left at 199009L and
no one builds kernels with a POSIX4 option.
.Pp
If you are working with something defined in POSIX.4 then there is a good
chance we conflict. If you have the time then set
_POSIX_VERSION to 199309L in /etc/make.conf and see that your work
fits with mine.
.Pp
Since this only brings in the headers I'm only explaining the feature
test options.
.Sh SPECIFYING THE VERSION
There are three manifest constants that set the version and programming interface
for POSIX.4.
.Bd -literal -offset 0i
_POSIX_VERSION
.Ed
specifies the system for which the system is built. The default
is POSIX.1 and is 199009L. POSIX.4 is 199309L. This defines
the base features of the operating system.
.Bd -literal -offset 0i
_POSIX_SOURCE
.Ed
is a macro from POSIX.1 that can
be defined to specify that only POSIX and ANSI functionality should occur
in the name space.
.Bd -literal -offset 0i
_POSIX_C_SOURCE
.Ed
is a macro from POSIX.4 that can be defined to specify that only
POSIX and ANSI functionality from a specific POSIX version should occur
in the name space, i.e., if _POSIX_VERSION is 199309L (POSIX.4) but
_POSIX_C_SOURCE is 199009L (POSIX.1) then only POSIX.1 features should
appear.
.Sh PROPERLY HIDING EXTENSIONS
.Bd -literal -offset 0i
POSIX4_VISIBLE
.Ed
is a test macro that tries to sort out when extensions should be
visible.
.Pp
In normal C program development
only _POSIX_VERSION is set, permitting BSD extensions to
appear to the programs. However, when adding new functionality mandated
by POSIX.4, it
is important to satisfy the requirements added by the
new _POSIX_C_SOURCE macro. POSIX4_VISIBLE (not a standard feature test macro)
is defined in sys/unistd.h when the combination of _POSIX_VERSION,
_POSIX_SOURCE, and _POSIX_C_SOURCE indicate the extensions are in scope.
.Pp
Since for POSIX to work you must include <unistd.h> which ultimately
sets this up header files can always assume this is visible without
including anything.
.Pp
Some traditional BSD headers (e.g., mmap.h) are now specified in POSIX.4.
This means that functionality not present in POSIX.4 should now be
hidden by testing _POSIX_SOURCE or _POSIX_C_SOURCE. The safest thing
is to hide them when _POSIX_C_SOURCE is defined and less than 199309L.
Don't bracket the extensions with the POSIX.4 feature test macros.
For example, don't conditionalize new memory locking flags with
_POSIX_MEMLOCK. It will be too easy for conflicting implementations
that don't pay heed to the POSIX.4 flags to sneak into the system.
.Sh NON STANDARD TEST MACROS
.Bd -literal -offset 0i
POSIX4_INCLUDE_MAYBES
.Ed
requests that all header files that the POSIX.4 spec says a standard
header may include should be included. Normally no non-required
headers are included. Setting this pre-processor definition should
make any compliant program compile without issues of header file
inclusion.
.Bd -literal -offset 0i
POSIX4
.Ed
is a config option and (currently) a request to build POSIX.4 by
setting the _POSIX_VERSION to 199309L in sys/unistd.h.
.Sh SEE ALSO
.Sh HISTORY
The
.Nm posix4
section manual page appeared in
.Fx 3.0 .
