606  * Previous releases of Solaris, starting at 2.3, provided definitions of
607  * various functions as specified in POSIX.1c, Draft 6.  For some of these
608  * functions, the final POSIX 1003.1c standard had a different number of
609  * arguments and return values.
610  *
611  * The following segment of this header provides support for the standard
612  * interfaces while supporting applications written under earlier
613  * releases.  The application defines appropriate values of the feature
614  * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
615  * whether it was written to expect the Draft 6 or standard versions of
616  * these interfaces, before including this header.  This header then
617  * provides a mapping from the source version of the interface to an
618  * appropriate binary interface.  Such mappings permit an application
619  * to be built from libraries and objects which have mixed expectations
620  * of the definitions of these functions.
621  *
622  * For applications using the Draft 6 definitions, the binary symbol is the
623  * same as the source symbol, and no explicit mapping is needed.  For the
624  * standard interface, the function func() is mapped to the binary symbol
625  * _posix_func().  The preferred mechanism for the remapping is a compiler
626  * #pragma.  If the compiler does not provide such a #pragma, the header file
627  * defines a static function func() which calls the _posix_func() version;
628  * this has to be done instead of #define since POSIX specifies that an
629  * application can #undef the symbol and still be bound to the correct
630  * implementation.  Unfortunately, the statics confuse lint so we fallback to
631  * #define in that case.
632  *
633  * NOTE: Support for the Draft 6 definitions is provided for compatibility
634  * only.  New applications/libraries should use the standard definitions.
