For some of these 892 * functions, the final POSIX 1003.1c standard had a different number of 893 * arguments and return values. 894 * 895 * The following segment of this header provides support for the standard 896 * interfaces while supporting applications written under earlier 897 * releases. The application defines appropriate values of the feature 898 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 899 * whether it was written to expect the Draft 6 or standard versions of 900 * these interfaces, before including this header. This header then 901 * provides a mapping from the source version of the interface to an 902 * appropriate binary interface. Such mappings permit an application 903 * to be built from libraries and objects which have mixed expectations 904 * of the definitions of these functions. 905 * 906 * For applications using the Draft 6 definitions, the binary symbol is the 907 * same as the source symbol, and no explicit mapping is needed. For the 908 * standard interface, the function func() is mapped to the binary symbol 909 * _posix_func(). The preferred mechanism for the remapping is a compiler 910 * #pragma. If the compiler does not provide such a #pragma, the header file 911 * defines a static function func() which calls the _posix_func() version; 912 * this has to be done instead of #define since POSIX specifies that an 913 * application can #undef the symbol and still be bound to the correct 914 * implementation. Unfortunately, the statics confuse lint so we fallback to 915 * #define in that case. 916 * 917 * NOTE: Support for the Draft 6 definitions is provided for compatibility 918 * only. New applications/libraries should use the standard definitions. 919 */ 920 921 #if defined(__EXTENSIONS__) || defined(_REENTRANT) || \ 922 !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 923 defined(_POSIX_PTHREAD_SEMANTICS) 924 925 #if defined(__STDC__) 926 927 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 928 929 #ifdef __PRAGMA_REDEFINE_EXTNAME 930 #pragma redefine_extname getlogin_r __posix_getlogin_r 931 #pragma redefine_extname ttyname_r __posix_ttyname_r 932 extern int getlogin_r(char *, int); 933 extern int ttyname_r(int, char *, size_t); 934 #else /* __PRAGMA_REDEFINE_EXTNAME */ 935 936 extern int __posix_getlogin_r(char *, int); 937 extern int __posix_ttyname_r(int, char *, size_t); 938 939 #ifdef __lint 940 941 #define getlogin_r __posix_getlogin_r 942 #define ttyname_r __posix_ttyname_r 943 944 #else /* !__lint */ 945 946 static int 947 getlogin_r(char *__name, int __len) 948 { 949 return (__posix_getlogin_r(__name, __len)); 950 } 951 static int 952 ttyname_r(int __fildes, char *__buf, size_t __size) 953 { 954 return (__posix_ttyname_r(__fildes, __buf, __size)); 955 } 956 957 #endif /* !__lint */ 958 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 959 960 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 961 962 extern char *getlogin_r(char *, int); 963 extern char *ttyname_r(int, char *, int); 964 965 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 966 967 #else /* __STDC__ */ 968 969 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 970 971 #ifdef __PRAGMA_REDEFINE_EXTNAME 972 #pragma redefine_extname getlogin_r __posix_getlogin_r 973 #pragma redefine_extname ttyname_r __posix_ttyname_r 974 extern int getlogin_r(); 975 extern int ttyname_r(); 976 #else /* __PRAGMA_REDEFINE_EXTNAME */ 977 978 extern int __posix_getlogin_r(); 979 extern int __posix_ttyname_r(); 980 981 #ifdef __lint 982 983 #define getlogin_r __posix_getlogin_r 984 #define ttyname_r __posix_ttyname_r 985 986 #else /* !__lint */ 987 988 static int 989 getlogin_r(__name, __len) 990 char *__name; 991 int __len; 992 { 993 return (__posix_getlogin_r(__name, __len)); 994 } 995 static int 996 ttyname_r(__fildes, __buf, __size) 997 int __fildes; 998 char *__buf; 999 size_t __size; 1000 { 1001 return (__posix_ttyname_r(__fildes, __buf, __size)); 1002 } 1003 #endif /* !__lint */ 1004 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 1005 1006 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 1007 1008 extern char *getlogin_r(); 1009 extern char *ttyname_r(); 1010 1011 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 1012 1013 #endif /* __STDC__ */ 1014 1015 #endif /* defined(__EXTENSIONS__) || defined(_REENTRANT)... */ 1016 1017 #ifdef __cplusplus 1018 } 1019 #endif 1020 1021 #endif /* _UNISTD_H */ 1022
