6007c478bd9Sstevel@tonic-gate  * Previous releases of Solaris, starting at 2.3, provided definitions of
6017c478bd9Sstevel@tonic-gate  * various functions as specified in POSIX.1c, Draft 6.  For some of these
6027c478bd9Sstevel@tonic-gate  * functions, the final POSIX 1003.1c standard had a different number of
6037c478bd9Sstevel@tonic-gate  * arguments and return values.
6047c478bd9Sstevel@tonic-gate  *
6057c478bd9Sstevel@tonic-gate  * The following segment of this header provides support for the standard
6067c478bd9Sstevel@tonic-gate  * interfaces while supporting applications written under earlier
6077c478bd9Sstevel@tonic-gate  * releases.  The application defines appropriate values of the feature
6087c478bd9Sstevel@tonic-gate  * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
6097c478bd9Sstevel@tonic-gate  * whether it was written to expect the Draft 6 or standard versions of
6107c478bd9Sstevel@tonic-gate  * these interfaces, before including this header.  This header then
6117c478bd9Sstevel@tonic-gate  * provides a mapping from the source version of the interface to an
6127c478bd9Sstevel@tonic-gate  * appropriate binary interface.  Such mappings permit an application
6137c478bd9Sstevel@tonic-gate  * to be built from libraries and objects which have mixed expectations
6147c478bd9Sstevel@tonic-gate  * of the definitions of these functions.
6157c478bd9Sstevel@tonic-gate  *
6167c478bd9Sstevel@tonic-gate  * For applications using the Draft 6 definitions, the binary symbol is the
6177c478bd9Sstevel@tonic-gate  * same as the source symbol, and no explicit mapping is needed.  For the
6187c478bd9Sstevel@tonic-gate  * standard interface, the function func() is mapped to the binary symbol
6197c478bd9Sstevel@tonic-gate  * _posix_func().  The preferred mechanism for the remapping is a compiler
6207c478bd9Sstevel@tonic-gate  * #pragma.  If the compiler does not provide such a #pragma, the header file
6217c478bd9Sstevel@tonic-gate  * defines a static function func() which calls the _posix_func() version;
6227c478bd9Sstevel@tonic-gate  * this has to be done instead of #define since POSIX specifies that an
6237c478bd9Sstevel@tonic-gate  * application can #undef the symbol and still be bound to the correct
6247c478bd9Sstevel@tonic-gate  * implementation.  Unfortunately, the statics confuse lint so we fallback to
6257c478bd9Sstevel@tonic-gate  * #define in that case.
6267c478bd9Sstevel@tonic-gate  *
6277c478bd9Sstevel@tonic-gate  * NOTE: Support for the Draft 6 definitions is provided for compatibility
6287c478bd9Sstevel@tonic-gate  * only.  New applications/libraries should use the standard definitions.
