102*0Sstevel@tonic-gate * Previous releases of Solaris, starting at 2.3, provided definitions of
103*0Sstevel@tonic-gate * various functions as specified in POSIX.1c, Draft 6. For some of these
104*0Sstevel@tonic-gate * functions, the final POSIX 1003.1c standard had a different number of
105*0Sstevel@tonic-gate * arguments and return values.
106*0Sstevel@tonic-gate *
107*0Sstevel@tonic-gate * The following segment of this header provides support for the standard
108*0Sstevel@tonic-gate * interfaces while supporting applications written under earlier
109*0Sstevel@tonic-gate * releases. The application defines appropriate values of the feature
110*0Sstevel@tonic-gate * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
111*0Sstevel@tonic-gate * whether it was written to expect the Draft 6 or standard versions of
112*0Sstevel@tonic-gate * these interfaces, before including this header. This header then
113*0Sstevel@tonic-gate * provides a mapping from the source version of the interface to an
114*0Sstevel@tonic-gate * appropriate binary interface. Such mappings permit an application
115*0Sstevel@tonic-gate * to be built from libraries and objects which have mixed expectations
116*0Sstevel@tonic-gate * of the definitions of these functions.
117*0Sstevel@tonic-gate *
118*0Sstevel@tonic-gate * For applications using the Draft 6 definitions, the binary symbol is the
119*0Sstevel@tonic-gate * same as the source symbol, and no explicit mapping is needed. For the
120*0Sstevel@tonic-gate * standard interface, the function func() is mapped to the binary symbol
121*0Sstevel@tonic-gate * _posix_func(). The preferred mechanism for the remapping is a compiler
122*0Sstevel@tonic-gate * #pragma. If the compiler does not provide such a #pragma, the header file
123*0Sstevel@tonic-gate * defines a static function func() which calls the _posix_func() version;
124*0Sstevel@tonic-gate * this has to be done instead of #define since POSIX specifies that an
125*0Sstevel@tonic-gate * application can #undef the symbol and still be bound to the correct
126*0Sstevel@tonic-gate * implementation. Unfortunately, the statics confuse lint so we fallback to
127*0Sstevel@tonic-gate * #define in that case.
128*0Sstevel@tonic-gate *
129*0Sstevel@tonic-gate * NOTE: Support for the Draft 6 definitions is provided for compatibility
130*0Sstevel@tonic-gate * only. New applications/libraries should use the standard definitions.
