/* Various options should be defined here, but the framework to do this
|
|
is not laid down so far. Especially notable are the following defines,
|
|
which can be used by the application to switch on or off various
|
|
datatypes and function prototypes:
|
|
|
|
_BSD_SOURCE to include pure BSD functions which are not defined
|
|
under POSIX.
|
|
|
|
_POSIX_SOURCE if the application requests a POSIX compatible system.
|
|
|
|
_XOPEN_SOURCE if X/Open functions and datatypes are requested. This
|
|
option includes _POSIX_SOURCE.
|
|
|
|
_GNU_SOURCE to turn on GNU extensions which might collide with defines
|
|
used in application or library headers. This option
|
|
includes _BSD_SOURCE, _XOPEN_SOURCE and _POSIX_SOURCE.
