600 * Previous releases of Solaris, starting at 2.3, provided definitions of
601 * various functions as specified in POSIX.1c, Draft 6. For some of these
602 * functions, the final POSIX 1003.1c standard had a different number of
603 * arguments and return values.
604 *
605 * The following segment of this header provides support for the standard
606 * interfaces while supporting applications written under earlier
607 * releases. The application defines appropriate values of the feature
608 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
609 * whether it was written to expect the Draft 6 or standard versions of
610 * these interfaces, before including this header. This header then
611 * provides a mapping from the source version of the interface to an
612 * appropriate binary interface. Such mappings permit an application
613 * to be built from libraries and objects which have mixed expectations
614 * of the definitions of these functions.
615 *
616 * For applications using the Draft 6 definitions, the binary symbol is the
617 * same as the source symbol, and no explicit mapping is needed. For the
618 * standard interface, the function func() is mapped to the binary symbol
619 * _posix_func(). The preferred mechanism for the remapping is a compiler
620 * #pragma. If the compiler does not provide such a #pragma, the header file
621 * defines a static function func() which calls the _posix_func() version;
622 * this has to be done instead of #define since POSIX specifies that an
623 * application can #undef the symbol and still be bound to the correct
624 * implementation. Unfortunately, the statics confuse lint so we fallback to
625 * #define in that case.
626 *
627 * NOTE: Support for the Draft 6 definitions is provided for compatibility
628 * only. New applications/libraries should use the standard definitions.
