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