| 902 /* | |
| 903 * Previous releases of Solaris, starting at 2.3, provided definitions of | |
| 904 * various functions as specified in POSIX.1c, Draft 6. For some of these | |
| 905 * functions, the final POSIX 1003.1c standard had a different number of | |
| 906 * arguments and return values. | |
| 907 * | |
| 908 * The following segment of this header provides support for the standard | |
| 909 * interfaces while supporting applications written under earlier | |
| 910 * releases. The application defines appropriate values of the feature | |
| 911 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate | |
| 912 * whether it was written to expect the Draft 6 or standard versions of | |
| 913 * these interfaces, before including this header. This header then | |
| 914 * provides a mapping from the source version of the interface to an | |
| 915 * appropriate binary interface. Such mappings permit an application | |
| 916 * to be built from libraries and objects which have mixed expectations | |
| 917 * of the definitions of these functions. | |
| 918 * | |
| 919 * For applications using the Draft 6 definitions, the binary symbol is the | |
| 920 * same as the source symbol, and no explicit mapping is needed. For the | |
| 921 * standard interface, the function func() is mapped to the binary symbol | |
| 922 * _posix_func(). The preferred mechanism for the remapping is a compiler | |
| 923 * #pragma. If the compiler does not provide such a #pragma, the header file | |
| 924 * defines a static function func() which calls the _posix_func() version; | |
| 925 * this has to be done instead of #define since POSIX specifies that an | |
| 926 * application can #undef the symbol and still be bound to the correct | |
| 927 * implementation. Unfortunately, the statics confuse lint so we fallback to | |
| 928 * #define in that case. | |
| 929 * | |
| 930 * NOTE: Support for the Draft 6 definitions is provided for compatibility | |
| 931 * only. New applications/libraries should use the standard definitions. | |
| 932 */ | |
