218 * COMPILATION ENVIRONMENTS
219 *
220 * DEFAULT By default newly complied code will get POSIX APIs plus
221 * Apple API extensions in scope.
222 *
223 * Most users will use this compilation environment to avoid
224 * behavioural differences between 32 and 64 bit code.
225 *
226 * LEGACY Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple
227 * API extensions in scope.
228 *
229 * This is generally equivalent to the Tiger release compilation
230 * environment, except that it cannot be applied to 64 bit code;
231 * its use is discouraged.
232 *
233 * We expect this environment to be deprecated in the future.
234 *
235 * STRICT Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the
236 * available APIs to exactly the set of APIs defined by the
237 * corresponding standard, based on the value defined.
91447636 238 *
2d21ac55
A
239 * A correct, portable definition for _POSIX_C_SOURCE is 200112L.
240 * A correct, portable definition for _XOPEN_SOURCE is 600L.
241 *
242 * Apple API extensions are not visible in this environment,
243 * which can cause Apple specific code to fail to compile,
244 * or behave incorrectly if prototypes are not in scope or
245 * warnings about missing prototypes are not enabled or ignored.
246 *
247 * In any compilation environment, for correct symbol resolution to occur,
248 * function prototypes must be in scope. It is recommended that all Apple
249 * tools users add etiher the "-Wall" or "-Wimplicit-function-declaration"
250 * compiler flags to their projects to be warned when a function is being
251 * used without a prototype in scope.

436 * POSIX.1 requires that the macros we test be defined before any standard
437 * header file is included. This permits us to convert values for feature
438 * testing, as necessary, using only _POSIX_C_SOURCE.
439 *
440 * Here's a quick run-down of the versions:
441 * defined(_POSIX_SOURCE) 1003.1-1988
442 * _POSIX_C_SOURCE == 1L 1003.1-1990
443 * _POSIX_C_SOURCE == 2L 1003.2-1992 C Language Binding Option
444 * _POSIX_C_SOURCE == 199309L 1003.1b-1993
445 * _POSIX_C_SOURCE == 199506L 1003.1c-1995, 1003.1i-1995,
446 * and the omnibus ISO/IEC 9945-1: 1996
447 * _POSIX_C_SOURCE == 200112L 1003.1-2001
448 *
449 * In addition, the X/Open Portability Guide, which is now the Single UNIX
450 * Specification, defines a feature-test macro which indicates the version of
451 * that specification, and which subsumes _POSIX_C_SOURCE.
