For some of these 897 * functions, the final POSIX 1003.1c standard had a different number of 898 * arguments and return values. 899 * 900 * The following segment of this header provides support for the standard 901 * interfaces while supporting applications written under earlier 902 * releases. The application defines appropriate values of the feature 903 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 904 * whether it was written to expect the Draft 6 or standard versions of 905 * these interfaces, before including this header. This header then 906 * provides a mapping from the source version of the interface to an 907 * appropriate binary interface. Such mappings permit an application 908 * to be built from libraries and objects which have mixed expectations 909 * of the definitions of these functions. 910 * 911 * For applications using the Draft 6 definitions, the binary symbol is the 912 * same as the source symbol, and no explicit mapping is needed. For the 913 * standard interface, the function func() is mapped to the binary symbol 914 * _posix_func(). The preferred mechanism for the remapping is a compiler 915 * #pragma. If the compiler does not provide such a #pragma, the header file 916 * defines a static function func() which calls the _posix_func() version; 917 * this has to be done instead of #define since POSIX specifies that an 918 * application can #undef the symbol and still be bound to the correct 919 * implementation. Unfortunately, the statics confuse lint so we fallback to 920 * #define in that case. 921 * 922 * NOTE: Support for the Draft 6 definitions is provided for compatibility 923 * only. New applications/libraries should use the standard definitions. 924 */ 925 926 #if defined(__EXTENSIONS__) || defined(_REENTRANT) || \ 927 !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 928 defined(_POSIX_PTHREAD_SEMANTICS) 929 930 #if defined(__STDC__) 931 932 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 933 934 #ifdef __PRAGMA_REDEFINE_EXTNAME 935 #pragma redefine_extname getlogin_r __posix_getlogin_r 936 #pragma redefine_extname ttyname_r __posix_ttyname_r 937 extern int getlogin_r(char *, int); 938 extern int ttyname_r(int, char *, size_t); 939 #else /* __PRAGMA_REDEFINE_EXTNAME */ 940 941 extern int __posix_getlogin_r(char *, int); 942 extern int __posix_ttyname_r(int, char *, size_t); 943 944 #ifdef __lint 945 946 #define getlogin_r __posix_getlogin_r 947 #define ttyname_r __posix_ttyname_r 948 949 #else /* !__lint */ 950 951 static int 952 getlogin_r(char *__name, int __len) 953 { 954 return (__posix_getlogin_r(__name, __len)); 955 } 956 static int 957 ttyname_r(int __fildes, char *__buf, size_t __size) 958 { 959 return (__posix_ttyname_r(__fildes, __buf, __size)); 960 } 961 962 #endif /* !__lint */ 963 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 964 965 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 966 967 extern char *getlogin_r(char *, int); 968 extern char *ttyname_r(int, char *, int); 969 970 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 971 972 #else /* __STDC__ */ 973 974 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 975 976 #ifdef __PRAGMA_REDEFINE_EXTNAME 977 #pragma redefine_extname getlogin_r __posix_getlogin_r 978 #pragma redefine_extname ttyname_r __posix_ttyname_r 979 extern int getlogin_r(); 980 extern int ttyname_r(); 981 #else /* __PRAGMA_REDEFINE_EXTNAME */ 982 983 extern int __posix_getlogin_r(); 984 extern int __posix_ttyname_r(); 985 986 #ifdef __lint 987 988 #define getlogin_r __posix_getlogin_r 989 #define ttyname_r __posix_ttyname_r 990 991 #else /* !__lint */ 992 993 static int 994 getlogin_r(__name, __len) 995 char *__name; 996 int __len; 997 { 998 return (__posix_getlogin_r(__name, __len)); 999 } 1000 static int 1001 ttyname_r(__fildes, __buf, __size) 1002 int __fildes; 1003 char *__buf; 1004 size_t __size; 1005 { 1006 return (__posix_ttyname_r(__fildes, __buf, __size)); 1007 } 1008 #endif /* !__lint */ 1009 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 1010 1011 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 1012 1013 extern char *getlogin_r(); 1014 extern char *ttyname_r(); 1015 1016 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 1017 1018 #endif /* __STDC__ */ 1019 1020 #endif /* defined(__EXTENSIONS__) || defined(_REENTRANT)... */ 1021 1022 #ifdef __cplusplus 1023 } 1024 #endif 1025 1026 #endif /* _UNISTD_H */ 1027
