For some of these 615 * functions, the final POSIX 1003.1c standard had a different number of 616 * arguments and return values. 617 * 618 * The following segment of this header provides support for the standard 619 * interfaces while supporting applications written under earlier 620 * releases. The application defines appropriate values of the feature 621 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 622 * whether it was written to expect the Draft 6 or standard versions of 623 * these interfaces, before including this header. This header then 624 * provides a mapping from the source version of the interface to an 625 * appropriate binary interface. Such mappings permit an application 626 * to be built from libraries and objects which have mixed expectations 627 * of the definitions of these functions. 628 * 629 * For applications using the Draft 6 definitions, the binary symbol is the 630 * same as the source symbol, and no explicit mapping is needed. For the 631 * standard interface, the function func() is mapped to the binary symbol 632 * _posix_func(). The preferred mechanism for the remapping is a compiler 633 * #pragma. If the compiler does not provide such a #pragma, the header file 634 * defines a static function func() which calls the _posix_func() version; 635 * this has to be done instead of #define since POSIX specifies that an 636 * application can #undef the symbol and still be bound to the correct 637 * implementation. Unfortunately, the statics confuse lint so we fallback to 638 * #define in that case. 639 * 640 * NOTE: Support for the Draft 6 definitions is provided for compatibility 641 * only. New applications/libraries should use the standard definitions. 642 */ 643 644 #if defined(__EXTENSIONS__) || defined(_REENTRANT) || \ 645 !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 646 defined(_POSIX_PTHREAD_SEMANTICS) 647 648 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 649 650 #ifndef __USE_LEGACY_LOGNAME__ 651 #ifdef __PRAGMA_REDEFINE_EXTNAME 652 #pragma redefine_extname getlogin_r __posix_getloginx_r 653 extern int getlogin_r(char *, int); 654 #else /* __PRAGMA_REDEFINE_EXTNAME */ 655 extern int __posix_getloginx_r(char *, int); 656 #define getlogin_r __posix_getloginx_r 657 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 658 #else /* __USE_LEGACY_LOGNAME__ */ 659 #ifdef __PRAGMA_REDEFINE_EXTNAME 660 #pragma redefine_extname getlogin_r __posix_getlogin_r 661 extern int getlogin_r(char *, int); 662 #else /* __PRAGMA_REDEFINE_EXTNAME */ 663 extern int __posix_getlogin_r(char *, int); 664 665 #ifdef __lint 666 667 #define getlogin_r __posix_getlogin_r 668 669 #else /* !__lint */ 670 671 static int 672 getlogin_r(char *__name, int __len) 673 { 674 return (__posix_getlogin_r(__name, __len)); 675 } 676 677 #endif /* !__lint */ 678 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 679 #endif /* __USE_LEGACY_LOGNAME__ */ 680 681 #ifdef __PRAGMA_REDEFINE_EXTNAME 682 #pragma redefine_extname ttyname_r __posix_ttyname_r 683 extern int ttyname_r(int, char *, size_t); 684 #else /* __PRAGMA_REDEFINE_EXTNAME */ 685 extern int __posix_ttyname_r(int, char *, size_t); 686 687 #ifdef __lint 688 689 #define ttyname_r __posix_ttyname_r 690 691 #else /* !__lint */ 692 693 static int 694 ttyname_r(int __fildes, char *__buf, size_t __size) 695 { 696 return (__posix_ttyname_r(__fildes, __buf, __size)); 697 } 698 699 #endif /* !__lint */ 700 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 701 702 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 703 704 #ifndef __USE_LEGACY_LOGNAME__ 705 #ifdef __PRAGMA_REDEFINE_EXTNAME 706 #pragma redefine_extname getlogin_r getloginx_r 707 #else /* __PRAGMA_REDEFINE_EXTNAME */ 708 extern char *getloginx_r(char *, int); 709 #define getlogin_r getloginx_r 710 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 711 #endif /* __USE_LEGACY_LOGNAME__ */ 712 extern char *getlogin_r(char *, int); 713 714 extern char *ttyname_r(int, char *, int); 715 716 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 717 718 #endif /* defined(__EXTENSIONS__) || defined(_REENTRANT)... */ 719 720 #ifdef __cplusplus 721 } 722 #endif 723 724 #endif /* _UNISTD_H */ 725
