613 610 * Previous releases of Solaris, starting at 2.3, provided definitions of
614 611 * various functions as specified in POSIX.1c, Draft 6. For some of these
615 612 * functions, the final POSIX 1003.1c standard had a different number of
616 613 * arguments and return values.
617 614 *
618 615 * The following segment of this header provides support for the standard
619 616 * interfaces while supporting applications written under earlier
620 617 * releases. The application defines appropriate values of the feature
621 618 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
622 619 * whether it was written to expect the Draft 6 or standard versions of
623 620 * these interfaces, before including this header. This header then
624 621 * provides a mapping from the source version of the interface to an
625 622 * appropriate binary interface. Such mappings permit an application
626 623 * to be built from libraries and objects which have mixed expectations
627 624 * of the definitions of these functions.
628 625 *
629 626 * For applications using the Draft 6 definitions, the binary symbol is the
630 627 * same as the source symbol, and no explicit mapping is needed. For the
631 628 * standard interface, the function func() is mapped to the binary symbol
632 629 * _posix_func(). The preferred mechanism for the remapping is a compiler
633 630 * #pragma. If the compiler does not provide such a #pragma, the header file
634 631 * defines a static function func() which calls the _posix_func() version;
635 632 * this has to be done instead of #define since POSIX specifies that an
636 633 * application can #undef the symbol and still be bound to the correct
637 634 * implementation. Unfortunately, the statics confuse lint so we fallback to
638 635 * #define in that case.
639 636 *
640 637 * NOTE: Support for the Draft 6 definitions is provided for compatibility
641 638 * only. New applications/libraries should use the standard definitions.
