-.Dt POSIX.1B 9
-.Os
-.Sh NAME
-.Nm posix1b
-.Nd "Posix P1003-1B extensions"
-.Sh DESCRIPTION
-POSIX.1B adds real time extensions and some commonly used
-Berkeley extensions to POSIX.1.
-This section contains preliminary information about avoiding conflicts
-and adding support for the required ability to specify the interface
-version.
-.Sh STATUS
-March 28, 1998: _POSIX_PRIORITY_SCHEDULING works with these kernel
-options in your configuration:
-.Bd -literal -offset 0i
-options		"P1003_1B"
-options		"_KPOSIX_PRIORITY_SCHEDULING"
-.Ed
-.Sh SPECIFYING THE VERSION
-There are three manifest constants that set the version and programming interface
-for POSIX.1B.
-.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.1B 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.1B 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.1B) but
-_POSIX_C_SOURCE is 199009L (POSIX.1) then only POSIX.1 features should
-appear.
-.Sh PROPERLY HIDING EXTENSIONS
-The following test macros are set up in <sys/_posix.h>.  They should
-used by system header files to avoid the kind of tests you see in
-<sys/_posix.h>.  Source programs should not use these
-.Fx
-specific
-implementation details and should test _POSIX_VERSION, _POSIX_SOURCE
-and _POSIX_C_SOURCE.
-These should not be used in the kernel though - the kernel should be
-immune to the user land setting of _POSIX_VERSION.  The P1003_1B option can
-be used in the kernel to limit inclusion of new code, but make sure
-things work properly when a POSIX.1B program is run on a kernel without
-the P1003_1B option.
-.Bd -literal -offset 0i
-_P1003_1B_VISIBLE
-.Ed
-is a test macro that sorts out when extensions should be
-visible.  It is defined in <sys/_posix.h>.
-.Pp
-In normal C program development
-only _POSIX_VERSION is set, permitting
-.Bx
-extensions to
-appear to the programs.  However, when adding new functionality mandated
-by POSIX.1B, it
-is important to satisfy the requirements added by the
-new _POSIX_C_SOURCE macro.  _P1003_1B_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 that the extensions are in scope.
-.Bd -literal -offset 0i
-_P1003_1B_VISIBLE_HISTORICALLY
-.Ed
-is present to conditionalize POSIX.1B extensions that were historically
-in the system.  These are visible when _POSIX_SOURCE and _POSIX_C_SOURCE
-are not set at all or when _POSIX_C_SOURCE enables POSIX.1B features.
-The intent of this feature test is to permit hiding the new extensions
-while still letting
-.Bx
-extensions show up to avoid breaking existing
-programs without trying to use the "big hammer" of _POSIX_C_SOURCE.
-.Pp
-Some recent additions to header files
-are new enough that they should be changed to
-be dependent on _P1003_1B_VISIBLE instead of _HISTORICALLY.
-.Pp
-Traditional
-.Bx
-headers (e.g., mmap.h) now specified
-in POSIX.1B can include <sys/_posix.h> and conditionalize
-.Bx
-extensions on _P1003_1B_VISIBLE_HISTORICALLY.
-.Sh NON STANDARD TEST MACROS
-.Bd -literal -offset 0i
-_P1003_1B_INCLUDE_MAYBES
-.Ed
-when set before the inclusion of any other header file
-requests that all header files that the POSIX.1B 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
-P1003_1B
-.Ed
-is a config option to build in POSIX.1B support in the kernel.
