890 * Previous releases of Solaris, starting at 2.3, provided definitions of
891 * various functions as specified in POSIX.1c, Draft 6. For some of these
892 * functions, the final POSIX 1003.1c standard had a different number of
893 * arguments and return values.
894 *
895 * The following segment of this header provides support for the standard
896 * interfaces while supporting applications written under earlier
897 * releases. The application defines appropriate values of the feature
898 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
899 * whether it was written to expect the Draft 6 or standard versions of
900 * these interfaces, before including this header. This header then
901 * provides a mapping from the source version of the interface to an
902 * appropriate binary interface. Such mappings permit an application
903 * to be built from libraries and objects which have mixed expectations
904 * of the definitions of these functions.
905 *
906 * For applications using the Draft 6 definitions, the binary symbol is the
907 * same as the source symbol, and no explicit mapping is needed. For the
908 * standard interface, the function func() is mapped to the binary symbol
909 * _posix_func(). The preferred mechanism for the remapping is a compiler
910 * #pragma. If the compiler does not provide such a #pragma, the header file
911 * defines a static function func() which calls the _posix_func() version;
912 * this has to be done instead of #define since POSIX specifies that an
913 * application can #undef the symbol and still be bound to the correct
914 * implementation. Unfortunately, the statics confuse lint so we fallback to
915 * #define in that case.
916 *
917 * NOTE: Support for the Draft 6 definitions is provided for compatibility
918 * only. New applications/libraries should use the standard definitions.
