895 * Previous releases of Solaris, starting at 2.3, provided definitions of
896 * various functions as specified in POSIX.1c, Draft 6. For some of these
897 * functions, the final POSIX 1003.1c standard had a different number of
898 * arguments and return values.
899 *
900 * The following segment of this header provides support for the standard
901 * interfaces while supporting applications written under earlier
902 * releases. The application defines appropriate values of the feature
903 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
904 * whether it was written to expect the Draft 6 or standard versions of
905 * these interfaces, before including this header. This header then
906 * provides a mapping from the source version of the interface to an
907 * appropriate binary interface. Such mappings permit an application
908 * to be built from libraries and objects which have mixed expectations
909 * of the definitions of these functions.
910 *
911 * For applications using the Draft 6 definitions, the binary symbol is the
912 * same as the source symbol, and no explicit mapping is needed. For the
913 * standard interface, the function func() is mapped to the binary symbol
914 * _posix_func(). The preferred mechanism for the remapping is a compiler
915 * #pragma. If the compiler does not provide such a #pragma, the header file
916 * defines a static function func() which calls the _posix_func() version;
917 * this has to be done instead of #define since POSIX specifies that an
918 * application can #undef the symbol and still be bound to the correct
919 * implementation. Unfortunately, the statics confuse lint so we fallback to
920 * #define in that case.
921 *
922 * NOTE: Support for the Draft 6 definitions is provided for compatibility
923 * only. New applications/libraries should use the standard definitions.
