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