For some of these 609 * functions, the final POSIX 1003.1c standard had a different number of 610 * arguments and return values. 611 * 612 * The following segment of this header provides support for the standard 613 * interfaces while supporting applications written under earlier 614 * releases. The application defines appropriate values of the feature 615 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 616 * whether it was written to expect the Draft 6 or standard versions of 617 * these interfaces, before including this header. This header then 618 * provides a mapping from the source version of the interface to an 619 * appropriate binary interface. Such mappings permit an application 620 * to be built from libraries and objects which have mixed expectations 621 * of the definitions of these functions. 622 * 623 * For applications using the Draft 6 definitions, the binary symbol is the 624 * same as the source symbol, and no explicit mapping is needed. For the 625 * standard interface, the function func() is mapped to the binary symbol 626 * _posix_func(). The preferred mechanism for the remapping is a compiler 627 * #pragma. If the compiler does not provide such a #pragma, the header file 628 * defines a static function func() which calls the _posix_func() version; 629 * this has to be done instead of #define since POSIX specifies that an 630 * application can #undef the symbol and still be bound to the correct 631 * implementation. Unfortunately, the statics confuse lint so we fallback to 632 * #define in that case. 633 * 634 * NOTE: Support for the Draft 6 definitions is provided for compatibility 635 * only. New applications/libraries should use the standard definitions. 636 */ 637 638 #if defined(__EXTENSIONS__) || defined(_REENTRANT) || \ 639 !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 640 defined(_POSIX_PTHREAD_SEMANTICS) 641 642 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 643 644 #ifndef __USE_LEGACY_LOGNAME__ 645 #ifdef __PRAGMA_REDEFINE_EXTNAME 646 #pragma redefine_extname getlogin_r __posix_getloginx_r 647 extern int getlogin_r(char *, int); 648 #else /* __PRAGMA_REDEFINE_EXTNAME */ 649 extern int __posix_getloginx_r(char *, int); 650 #define getlogin_r __posix_getloginx_r 651 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 652 #else /* __USE_LEGACY_LOGNAME__ */ 653 #ifdef __PRAGMA_REDEFINE_EXTNAME 654 #pragma redefine_extname getlogin_r __posix_getlogin_r 655 extern int getlogin_r(char *, int); 656 #else /* __PRAGMA_REDEFINE_EXTNAME */ 657 extern int __posix_getlogin_r(char *, int); 658 659 #ifdef __lint 660 661 #define getlogin_r __posix_getlogin_r 662 663 #else /* !__lint */ 664 665 static int 666 getlogin_r(char *__name, int __len) 667 { 668 return (__posix_getlogin_r(__name, __len)); 669 } 670 671 #endif /* !__lint */ 672 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 673 #endif /* __USE_LEGACY_LOGNAME__ */ 674 675 #ifdef __PRAGMA_REDEFINE_EXTNAME 676 #pragma redefine_extname ttyname_r __posix_ttyname_r 677 extern int ttyname_r(int, char *, size_t); 678 #else /* __PRAGMA_REDEFINE_EXTNAME */ 679 extern int __posix_ttyname_r(int, char *, size_t); 680 681 #ifdef __lint 682 683 #define ttyname_r __posix_ttyname_r 684 685 #else /* !__lint */ 686 687 static int 688 ttyname_r(int __fildes, char *__buf, size_t __size) 689 { 690 return (__posix_ttyname_r(__fildes, __buf, __size)); 691 } 692 693 #endif /* !__lint */ 694 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 695 696 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 697 698 #ifndef __USE_LEGACY_LOGNAME__ 699 #ifdef __PRAGMA_REDEFINE_EXTNAME 700 #pragma redefine_extname getlogin_r getloginx_r 701 #else /* __PRAGMA_REDEFINE_EXTNAME */ 702 extern char *getloginx_r(char *, int); 703 #define getlogin_r getloginx_r 704 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 705 #endif /* __USE_LEGACY_LOGNAME__ */ 706 extern char *getlogin_r(char *, int); 707 708 extern char *ttyname_r(int, char *, int); 709 710 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 711 712 #endif /* defined(__EXTENSIONS__) || defined(_REENTRANT)... */ 713 714 #if !defined(_STRICT_SYMBOLS) 715 extern int getentropy(void *, size_t); 716 #endif /* !_STRICT_SYMBOLS */ 717 718 #ifdef __cplusplus 719 } 720 #endif 721 722 #endif /* _UNISTD_H */ 723
