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. | |
252 | */ | |
253 | ||
254 | /* | |
255 | * The __DARWIN_ALIAS macros are used to do symbol renaming; they allow | |
256 | * legacy code to use the old symbol, thus maintiang binary compatability | |
257 | * while new code can use a standards compliant version of the same function. | |
91447636 A |
258 | * |
259 | * __DARWIN_ALIAS is used by itself if the function signature has not | |
260 | * changed, it is used along with a #ifdef check for __DARWIN_UNIX03 | |
261 | * if the signature has changed. Because the __LP64__ enviroment | |
262 | * only supports UNIX03 sementics it causes __DARWIN_UNIX03 to be | |
263 | * defined, but causes __DARWIN_ALIAS to do no symbol mangling. | |
2d21ac55 A |
264 | * |
265 | * As a special case, when XCode is used to target a specific version of the | |
266 | * OS, the manifest constant __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__ | |
267 | * will be defined by the compiler, with the digits representing major version | |
268 | * time 100 + minor version times 10 (e.g. 10.5 := 1050). If we are targetting | |
269 | * pre-10.5, and it is the default compilation environment, revert the | |
270 | * compilation environment to pre-__DARWIN_UNIX03. | |
