91 * Previous releases of Solaris, starting at 2.3, provided definitions of
92 * various functions as specified in POSIX.1c, Draft 6.  For some of these
93 * functions, the final POSIX 1003.1c standard had a different number of
94 * arguments and return values.
95 *
96 * The following segment of this header provides support for the standard
97 * interfaces while supporting applications written under earlier
98 * releases.  The application defines appropriate values of the feature
99 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
100 * whether it was written to expect the Draft 6 or standard versions of
101 * these interfaces, before including this header.  This header then
102 * provides a mapping from the source version of the interface to an
103 * appropriate binary interface.  Such mappings permit an application
104 * to be built from libraries and objects which have mixed expectations
105 * of the definitions of these functions.
106 *
107 * For applications using the Draft 6 definitions, the binary symbol is the
108 * same as the source symbol, and no explicit mapping is needed.  For the
109 * standard interface, the function func() is mapped to the binary symbol
110 * _posix_func().  The preferred mechanism for the remapping is a compiler
111 * #pragma.  If the compiler does not provide such a #pragma, the header file
112 * defines a static function func() which calls the _posix_func() version;
113 * this has to be done instead of #define since POSIX specifies that an
114 * application can #undef the symbol and still be bound to the correct
115 * implementation.  Unfortunately, the statics confuse lint so we fallback to
116 * #define in that case.
117 *
118 * NOTE: Support for the Draft 6 definitions is provided for compatibility
119 * only.  New applications/libraries should use the standard definitions.
