For some of these 608 * functions, the final POSIX 1003.1c standard had a different number of 609 * arguments and return values. 610 * 611 * The following segment of this header provides support for the standard 612 * interfaces while supporting applications written under earlier 613 * releases. The application defines appropriate values of the feature 614 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 615 * whether it was written to expect the Draft 6 or standard versions of 616 * these interfaces, before including this header. This header then 617 * provides a mapping from the source version of the interface to an 618 * appropriate binary interface. Such mappings permit an application 619 * to be built from libraries and objects which have mixed expectations 620 * of the definitions of these functions. 621 * 622 * For applications using the Draft 6 definitions, the binary symbol is the 623 * same as the source symbol, and no explicit mapping is needed. For the 624 * standard interface, the function func() is mapped to the binary symbol 625 * _posix_func(). The preferred mechanism for the remapping is a compiler 626 * #pragma. If the compiler does not provide such a #pragma, the header file 627 * defines a static function func() which calls the _posix_func() version; 628 * this has to be done instead of #define since POSIX specifies that an 629 * application can #undef the symbol and still be bound to the correct 630 * implementation. Unfortunately, the statics confuse lint so we fallback to 631 * #define in that case. 632 * 633 * NOTE: Support for the Draft 6 definitions is provided for compatibility 634 * only. New applications/libraries should use the standard definitions. 635 */ 636 637 #if defined(__EXTENSIONS__) || defined(_REENTRANT) || \ 638 !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 639 defined(_POSIX_PTHREAD_SEMANTICS) 640 641 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 642 643 #ifndef __USE_LEGACY_LOGNAME__ 644 #ifdef __PRAGMA_REDEFINE_EXTNAME 645 #pragma redefine_extname getlogin_r __posix_getloginx_r 646 extern int getlogin_r(char *, int); 647 #else /* __PRAGMA_REDEFINE_EXTNAME */ 648 extern int __posix_getloginx_r(char *, int); 649 #define getlogin_r __posix_getloginx_r 650 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 651 #else /* __USE_LEGACY_LOGNAME__ */ 652 #ifdef __PRAGMA_REDEFINE_EXTNAME 653 #pragma redefine_extname getlogin_r __posix_getlogin_r 654 extern int getlogin_r(char *, int); 655 #else /* __PRAGMA_REDEFINE_EXTNAME */ 656 extern int __posix_getlogin_r(char *, int); 657 658 #ifdef __lint 659 660 #define getlogin_r __posix_getlogin_r 661 662 #else /* !__lint */ 663 664 static int 665 getlogin_r(char *__name, int __len) 666 { 667 return (__posix_getlogin_r(__name, __len)); 668 } 669 670 #endif /* !__lint */ 671 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 672 #endif /* __USE_LEGACY_LOGNAME__ */ 673 674 #ifdef __PRAGMA_REDEFINE_EXTNAME 675 #pragma redefine_extname ttyname_r __posix_ttyname_r 676 extern int ttyname_r(int, char *, size_t); 677 #else /* __PRAGMA_REDEFINE_EXTNAME */ 678 extern int __posix_ttyname_r(int, char *, size_t); 679 680 #ifdef __lint 681 682 #define ttyname_r __posix_ttyname_r 683 684 #else /* !__lint */ 685 686 static int 687 ttyname_r(int __fildes, char *__buf, size_t __size) 688 { 689 return (__posix_ttyname_r(__fildes, __buf, __size)); 690 } 691 692 #endif /* !__lint */ 693 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 694 695 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 696 697 #ifndef __USE_LEGACY_LOGNAME__ 698 #ifdef __PRAGMA_REDEFINE_EXTNAME 699 #pragma redefine_extname getlogin_r getloginx_r 700 #else /* __PRAGMA_REDEFINE_EXTNAME */ 701 extern char *getloginx_r(char *, int); 702 #define getlogin_r getloginx_r 703 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 704 #endif /* __USE_LEGACY_LOGNAME__ */ 705 extern char *getlogin_r(char *, int); 706 707 extern char *ttyname_r(int, char *, int); 708 709 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 710 711 #endif /* defined(__EXTENSIONS__) || defined(_REENTRANT)... */ 712 713 #if !defined(_STRICT_SYMBOLS) 714 extern int getentropy(void *, size_t); 715 #endif /* !_STRICT_SYMBOLS */ 716 717 #ifdef __cplusplus 718 } 719 #endif 720 721 #endif /* _UNISTD_H */ 722
