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