931 589 * Previous releases of Solaris, starting at 2.3, provided definitions of
932 590 * various functions as specified in POSIX.1c, Draft 6. For some of these
933 591 * functions, the final POSIX 1003.1c standard had a different number of
934 592 * arguments and return values.
935 593 *
936 594 * The following segment of this header provides support for the standard
937 595 * interfaces while supporting applications written under earlier
938 596 * releases. The application defines appropriate values of the feature
939 597 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
940 598 * whether it was written to expect the Draft 6 or standard versions of
941 599 * these interfaces, before including this header. This header then
942 600 * provides a mapping from the source version of the interface to an
943 601 * appropriate binary interface. Such mappings permit an application
944 602 * to be built from libraries and objects which have mixed expectations
945 603 * of the definitions of these functions.
946 604 *
947 605 * For applications using the Draft 6 definitions, the binary symbol is the
948 606 * same as the source symbol, and no explicit mapping is needed. For the
949 607 * standard interface, the function func() is mapped to the binary symbol
950 608 * _posix_func(). The preferred mechanism for the remapping is a compiler
951 609 * #pragma. If the compiler does not provide such a #pragma, the header file
952 610 * defines a static function func() which calls the _posix_func() version;
953 611 * this has to be done instead of #define since POSIX specifies that an
954 612 * application can #undef the symbol and still be bound to the correct
955 613 * implementation. Unfortunately, the statics confuse lint so we fallback to

959 617 * only. New applications/libraries should use the standard definitions.
