613 616 * Previous releases of Solaris, starting at 2.3, provided definitions of
614 617 * various functions as specified in POSIX.1c, Draft 6. For some of these
615 618 * functions, the final POSIX 1003.1c standard had a different number of
616 619 * arguments and return values.
617 620 *
618 621 * The following segment of this header provides support for the standard
619 622 * interfaces while supporting applications written under earlier
620 623 * releases. The application defines appropriate values of the feature
621 624 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
622 625 * whether it was written to expect the Draft 6 or standard versions of
623 626 * these interfaces, before including this header. This header then
624 627 * provides a mapping from the source version of the interface to an
625 628 * appropriate binary interface. Such mappings permit an application
626 629 * to be built from libraries and objects which have mixed expectations
627 630 * of the definitions of these functions.
628 631 *
629 632 * For applications using the Draft 6 definitions, the binary symbol is the
630 633 * same as the source symbol, and no explicit mapping is needed. For the
631 634 * standard interface, the function func() is mapped to the binary symbol
632 635 * _posix_func(). The preferred mechanism for the remapping is a compiler
633 636 * #pragma. If the compiler does not provide such a #pragma, the header file
634 637 * defines a static function func() which calls the _posix_func() version;
635 638 * this has to be done instead of #define since POSIX specifies that an
636 639 * application can #undef the symbol and still be bound to the correct
637 640 * implementation. Unfortunately, the statics confuse lint so we fallback to
638 641 * #define in that case.
639 642 *
640 643 * NOTE: Support for the Draft 6 definitions is provided for compatibility
641 644 * only. New applications/libraries should use the standard definitions.
