For some of these 93 * functions, the final POSIX 1003.1c standard had a different number of 94 * arguments and return values. 95 * 96 * The following segment of this header provides support for the standard 97 * interfaces while supporting applications written under earlier 98 * releases. The application defines appropriate values of the feature 99 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 100 * whether it was written to expect the Draft 6 or standard versions of 101 * these interfaces, before including this header. This header then 102 * provides a mapping from the source version of the interface to an 103 * appropriate binary interface. Such mappings permit an application 104 * to be built from libraries and objects which have mixed expectations 105 * of the definitions of these functions. 106 * 107 * For applications using the Draft 6 definitions, the binary symbol is the 108 * same as the source symbol, and no explicit mapping is needed. For the 109 * standard interface, the function func() is mapped to the binary symbol 110 * _posix_func(). The preferred mechanism for the remapping is a compiler 111 * #pragma. If the compiler does not provide such a #pragma, the header file 112 * defines a static function func() which calls the _posix_func() version; 113 * this has to be done instead of #define since POSIX specifies that an 114 * application can #undef the symbol and still be bound to the correct 115 * implementation. Unfortunately, the statics confuse lint so we fallback to 116 * #define in that case. 117 * 118 * NOTE: Support for the Draft 6 definitions is provided for compatibility 119 * only. New applications/libraries should use the standard definitions. 120 */ 121 122 #if !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 123 defined(_POSIX_PTHREAD_SEMANTICS) || defined(__EXTENSIONS__) 124 125 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 126 127 #ifdef __PRAGMA_REDEFINE_EXTNAME 128 #pragma redefine_extname getpwuid_r __posix_getpwuid_r 129 #pragma redefine_extname getpwnam_r __posix_getpwnam_r 130 extern int getpwuid_r(uid_t, struct passwd *, char *, int, struct passwd **); 131 extern int getpwnam_r(const char *, struct passwd *, char *, 132 int, struct passwd **); 133 #else /* __PRAGMA_REDEFINE_EXTNAME */ 134 135 extern int __posix_getpwuid_r(uid_t, struct passwd *, char *, size_t, 136 struct passwd **); 137 extern int __posix_getpwnam_r(const char *, struct passwd *, char *, 138 size_t, struct passwd **); 139 140 #ifdef __lint 141 142 #define getpwuid_r __posix_getpwuid_r 143 #define getpwnam_r __posix_getpwnam_r 144 145 #else /* !__lint */ 146 147 static int 148 getpwuid_r(uid_t __uid, struct passwd *__pwd, char *__buf, int __len, 149 struct passwd **__res) 150 { 151 return (__posix_getpwuid_r(__uid, __pwd, __buf, __len, __res)); 152 } 153 static int 154 getpwnam_r(const char *__cb, struct passwd *__pwd, char *__buf, int __len, 155 struct passwd **__res) 156 { 157 return (__posix_getpwnam_r(__cb, __pwd, __buf, __len, __res)); 158 } 159 160 #endif /* !__lint */ 161 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 162 163 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 164 165 extern struct passwd *getpwuid_r(uid_t, struct passwd *, char *, int); 166 extern struct passwd *getpwnam_r(const char *, struct passwd *, char *, int); 167 168 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 169 170 #endif /* !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L)... */ 171 172 #ifdef __cplusplus 173 } 174 #endif 175 176 #endif /* _PWD_H */ 177
