| 395 | * DEFAULT By default newly complied code will get POSIX APIs plus |
| 396 | * Apple API extensions in scope. |
| 397 | * |
| 398 | * Most users will use this compilation environment to avoid |
| 399 | * behavioral differences between 32 and 64 bit code. |
| 400 | * |
| 401 | * LEGACY Defining _NONSTD_SOURCE will get pre-POSIX APIs plus Apple |
| 402 | * API extensions in scope. |
| 403 | * |
| 404 | * This is generally equivalent to the Tiger release compilation |
| 405 | * environment, except that it cannot be applied to 64 bit code; |
| 406 | * its use is discouraged. |
| 407 | * |
| 408 | * We expect this environment to be deprecated in the future. |
| 409 | * |
| 410 | * STRICT Defining _POSIX_C_SOURCE or _XOPEN_SOURCE restricts the |
| 411 | * available APIs to exactly the set of APIs defined by the |
| 412 | * corresponding standard, based on the value defined. |
| 413 | * |
| 414 | * A correct, portable definition for _POSIX_C_SOURCE is 200112L. |
| 415 | * A correct, portable definition for _XOPEN_SOURCE is 600L. |
| 416 | * |
| 417 | * Apple API extensions are not visible in this environment, |
| 418 | * which can cause Apple specific code to fail to compile, |
| 419 | * or behave incorrectly if prototypes are not in scope or |
| 420 | * warnings about missing prototypes are not enabled or ignored. |
| 421 | * |
| 422 | * In any compilation environment, for correct symbol resolution to occur, |
| 423 | * function prototypes must be in scope. It is recommended that all Apple |
| 424 | * tools users add either the "-Wall" or "-Wimplicit-function-declaration" |
| 425 | * compiler flags to their projects to be warned when a function is being |
| 426 | * used without a prototype in scope. |
