931 * Previous releases of Solaris, starting at 2.3, provided definitions of

933 * functions, the final POSIX 1003.1c standard had a different number of
934 * arguments and return values.
935 *
936 * The following segment of this header provides support for the standard
937 * interfaces while supporting applications written under earlier
938 * releases. The application defines appropriate values of the feature
939 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
940 * whether it was written to expect the Draft 6 or standard versions of
941 * these interfaces, before including this header. This header then
942 * provides a mapping from the source version of the interface to an
946 *
947 * For applications using the Draft 6 definitions, the binary symbol is the
948 * same as the source symbol, and no explicit mapping is needed. For the
949 * standard interface, the function func() is mapped to the binary symbol
950 * _posix_func(). The preferred mechanism for the remapping is a compiler
951 * #pragma. If the compiler does not provide such a #pragma, the header file
952 * defines a static function func() which calls the _posix_func() version;
953 * this has to be done instead of #define since POSIX specifies that an
954 * application can #undef the symbol and still be bound to the correct
955 * implementation. Unfortunately, the statics confuse lint so we fallback to
956 * #define in that case.
957 *
958 * NOTE: Support for the Draft 6 definitions is provided for compatibility
959 * only. New applications/libraries should use the standard definitions.

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