204 * Previous releases of Solaris, starting at 2.3, provided definitions of
205 * various functions as specified in POSIX.1c, Draft 6. For some of these
206 * functions, the final POSIX 1003.1c standard had a different number of
207 * arguments and return values.
208 *
209 * The following segment of this header provides support for the standard
210 * interfaces while supporting applications written under earlier
211 * releases. The application defines appropriate values of the feature
212 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
213 * whether it was written to expect the Draft 6 or standard versions of
214 * these interfaces, before including this header. This header then
215 * provides a mapping from the source version of the interface to an
216 * appropriate binary interface. Such mappings permit an application
217 * to be built from libraries and objects which have mixed expectations
218 * of the definitions of these functions.
219 *
220 * For applications using the Draft 6 definitions, the binary symbol is the
221 * same as the source symbol, and no explicit mapping is needed. For the
222 * standard interface, the function func() is mapped to the binary symbol
223 * _posix_func(). The preferred mechanism for the remapping is a compiler
224 * #pragma. If the compiler does not provide such a #pragma, the header file
225 * defines a static function func() which calls the _posix_func() version;
226 * this has to be done instead of #define since POSIX specifies that an
227 * application can #undef the symbol and still be bound to the correct
228 * implementation. Unfortunately, the statics confuse lint so we fallback to
229 * #define in that case.
230 *
231 * NOTE: Support for the Draft 6 definitions is provided for compatibility
232 * only. New applications/libraries should use the standard definitions.
