 931  * Previous releases of Solaris, starting at 2.3, provided definitions of
 932  * various functions as specified in POSIX.1c, Draft 6.  For some of these
 933  * functions, the final POSIX 1003.1c standard had a different number of
 934  * arguments and return values.
 935  *
 936  * The following segment of this header provides support for the standard
 937  * interfaces while supporting applications written under earlier
 938  * releases.  The application defines appropriate values of the feature
 939  * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
 940  * whether it was written to expect the Draft 6 or standard versions of
 941  * these interfaces, before including this header.  This header then
 942  * provides a mapping from the source version of the interface to an
 943  * appropriate binary interface.  Such mappings permit an application
 944  * to be built from libraries and objects which have mixed expectations
 945  * of the definitions of these functions.
 946  *
 947  * For applications using the Draft 6 definitions, the binary symbol is the
 948  * same as the source symbol, and no explicit mapping is needed.  For the
 949  * standard interface, the function func() is mapped to the binary symbol
 950  * _posix_func().  The preferred mechanism for the remapping is a compiler
 951  * #pragma.  If the compiler does not provide such a #pragma, the header file
 952  * defines a static function func() which calls the _posix_func() version;
 953  * this has to be done instead of #define since POSIX specifies that an
 954  * application can #undef the symbol and still be bound to the correct
 955  * implementation.  Unfortunately, the statics confuse lint so we fallback to
 956  * #define in that case.
 957  *
 958  * NOTE: Support for the Draft 6 definitions is provided for compatibility
 959  * only.  New applications/libraries should use the standard definitions.

 588 /*
 589  * Previous releases of Solaris, starting at 2.3, provided definitions of
 590  * various functions as specified in POSIX.1c, Draft 6.  For some of these
 591  * functions, the final POSIX 1003.1c standard had a different number of
 592  * arguments and return values.
 593  *
 594  * The following segment of this header provides support for the standard
 595  * interfaces while supporting applications written under earlier
 596  * releases.  The application defines appropriate values of the feature
 597  * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate
 598  * whether it was written to expect the Draft 6 or standard versions of
 599  * these interfaces, before including this header.  This header then
 600  * provides a mapping from the source version of the interface to an
 601  * appropriate binary interface.  Such mappings permit an application
 602  * to be built from libraries and objects which have mixed expectations
 603  * of the definitions of these functions.
 604  *
 605  * For applications using the Draft 6 definitions, the binary symbol is the
 606  * same as the source symbol, and no explicit mapping is needed.  For the
 607  * standard interface, the function func() is mapped to the binary symbol
 608  * _posix_func().  The preferred mechanism for the remapping is a compiler
 609  * #pragma.  If the compiler does not provide such a #pragma, the header file
 610  * defines a static function func() which calls the _posix_func() version;
 611  * this has to be done instead of #define since POSIX specifies that an
 612  * application can #undef the symbol and still be bound to the correct
 613  * implementation.  Unfortunately, the statics confuse lint so we fallback to
 614  * #define in that case.
 615  *
 616  * NOTE: Support for the Draft 6 definitions is provided for compatibility
 617  * only.  New applications/libraries should use the standard definitions.
