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