882 * Previous releases of Solaris, starting at 2.3, provided definitions of
883 * various functions as specified in POSIX.1c, Draft 6.  For some of these
884 * functions, the final POSIX 1003.1c standard had a different number of
885 * arguments and return values.
886 *
887 * The following segment of this header provides support for the standard
888 * interfaces while supporting applications written under earlier
889 * releases.  The application defines appropriate values of the feature
890 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
891 * whether it was written to expect the Draft 6 or standard versions of
892 * these interfaces, before including this header.  This header then
893 * provides a mapping from the source version of the interface to an
894 * appropriate binary interface.  Such mappings permit an application
895 * to be built from libraries and objects which have mixed expectations
896 * of the definitions of these functions.
897 *
898 * For applications using the Draft 6 definitions, the binary symbol is the
899 * same as the source symbol, and no explicit mapping is needed.  For the
900 * standard interface, the function func() is mapped to the binary symbol
901 * _posix_func().  The preferred mechanism for the remapping is a compiler
902 * #pragma.  If the compiler does not provide such a #pragma, the header file
903 * defines a static function func() which calls the _posix_func() version;
904 * this has to be done instead of #define since POSIX specifies that an
905 * application can #undef the symbol and still be bound to the correct
906 * implementation.  Unfortunately, the statics confuse lint so we fallback to
907 * #define in that case.
908 *
909 * NOTE: Support for the Draft 6 definitions is provided for compatibility
910 * only.  New applications/libraries should use the standard definitions.
