114/*
115 * Previous releases of Solaris, starting at 2.3, provided definitions of
116 * various functions as specified in POSIX.1c, Draft 6.  For some of these
117 * functions, the final POSIX 1003.1c standard had a different number of
118 * arguments and return values.
119 *
120 * The following segment of this header provides support for the standard
121 * interfaces while supporting applications written under earlier
122 * releases.  The application defines appropriate values of the feature
123 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
124 * whether it was written to expect the Draft 6 or standard versions of
125 * these interfaces, before including this header.  This header then
126 * provides a mapping from the source version of the interface to an
127 * appropriate binary interface.  Such mappings permit an application
128 * to be built from libraries and objects which have mixed expectations
129 * of the definitions of these functions.
130 *
131 * For applications using the Draft 6 definitions, the binary symbol is the
132 * same as the source symbol, and no explicit mapping is needed.  For the
133 * standard interface, the function func() is mapped to the binary symbol
134 * _posix_func().  The preferred mechanism for the remapping is a compiler
135 * #pragma.  If the compiler does not provide such a #pragma, the header file
136 * defines a static function func() which calls the _posix_func() version;
137 * this has to be done instead of #define since POSIX specifies that an
138 * application can #undef the symbol and still be bound to the correct
139 * implementation.  Unfortunately, the statics confuse lint so we fallback to
140 * #define in that case.
141 *
142 * NOTE: Support for the Draft 6 definitions is provided for compatibility
143 * only.  New applications/libraries should use the standard definitions.
