For some of these 117 * functions, the final POSIX 1003.1c standard had a different number of 118 * arguments and return values. 119 * 120 * The following segment of this header provides support for the standard 121 * interfaces while supporting applications written under earlier 122 * releases. The application defines appropriate values of the feature 123 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 124 * whether it was written to expect the Draft 6 or standard versions of 125 * these interfaces, before including this header. This header then 126 * provides a mapping from the source version of the interface to an 127 * appropriate binary interface. Such mappings permit an application 128 * to be built from libraries and objects which have mixed expectations 129 * of the definitions of these functions. 130 * 131 * For applications using the Draft 6 definitions, the binary symbol is the 132 * same as the source symbol, and no explicit mapping is needed. For the 133 * standard interface, the function func() is mapped to the binary symbol 134 * _posix_func(). The preferred mechanism for the remapping is a compiler 135 * #pragma. If the compiler does not provide such a #pragma, the header file 136 * defines a static function func() which calls the _posix_func() version; 137 * this has to be done instead of #define since POSIX specifies that an 138 * application can #undef the symbol and still be bound to the correct 139 * implementation. Unfortunately, the statics confuse lint so we fallback to 140 * #define in that case. 141 * 142 * NOTE: Support for the Draft 6 definitions is provided for compatibility 143 * only. New applications/libraries should use the standard definitions. 144 */ 145 146 #if !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L) || \ 147 defined(_POSIX_PTHREAD_SEMANTICS) || defined(__EXTENSIONS__) 148 149 #if defined(__STDC__) 150 151 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 152 153 #ifdef __PRAGMA_REDEFINE_EXTNAME 154 #pragma redefine_extname getpwuid_r __posix_getpwuid_r 155 #pragma redefine_extname getpwnam_r __posix_getpwnam_r 156 extern int getpwuid_r(uid_t, struct passwd *, char *, int, struct passwd **); 157 extern int getpwnam_r(const char *, struct passwd *, char *, 158 int, struct passwd **); 159 #else /* __PRAGMA_REDEFINE_EXTNAME */ 160 161 extern int __posix_getpwuid_r(uid_t, struct passwd *, char *, size_t, 162 struct passwd **); 163 extern int __posix_getpwnam_r(const char *, struct passwd *, char *, 164 size_t, struct passwd **); 165 166 #ifdef __lint 167 168 #define getpwuid_r __posix_getpwuid_r 169 #define getpwnam_r __posix_getpwnam_r 170 171 #else /* !__lint */ 172 173 static int 174 getpwuid_r(uid_t __uid, struct passwd *__pwd, char *__buf, int __len, 175 struct passwd **__res) 176 { 177 return (__posix_getpwuid_r(__uid, __pwd, __buf, __len, __res)); 178 } 179 static int 180 getpwnam_r(const char *__cb, struct passwd *__pwd, char *__buf, int __len, 181 struct passwd **__res) 182 { 183 return (__posix_getpwnam_r(__cb, __pwd, __buf, __len, __res)); 184 } 185 186 #endif /* !__lint */ 187 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 188 189 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 190 191 extern struct passwd *getpwuid_r(uid_t, struct passwd *, char *, int); 192 extern struct passwd *getpwnam_r(const char *, struct passwd *, char *, int); 193 194 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 195 196 #else /* __STDC__ */ 197 198 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 199 200 #ifdef __PRAGMA_REDEFINE_EXTNAME 201 #pragma redefine_extname getpwuid_r __posix_getpwuid_r 202 #pragma redefine_extname getpwnam_r __posix_getpwnam_r 203 extern int getpwuid_r(); 204 extern int getpwnam_r(); 205 #else /* __PRAGMA_REDEFINE_EXTNAME */ 206 207 extern int __posix_getpwuid_r(); 208 extern int __posix_getpwnam_r(); 209 210 #ifdef __lint 211 212 #define getpwuid_r __posix_getpwuid_r 213 #define getpwnam_r __posix_getpwnam_r 214 215 #else /* !__lint */ 216 217 static int 218 getpwuid_r(__uid, __pwd, __buf, __len, __res) 219 uid_t __uid; 220 struct passwd *__pwd; 221 char *__buf; 222 int __len; 223 struct passwd **__res; 224 { 225 return (__posix_getpwuid_r(__uid, __pwd, __buf, __len, __res)); 226 } 227 static int 228 getpwnam_r(__cb, __pwd, __buf, __len, __res) 229 char *__cb; 230 struct passwd *__pwd; 231 char *__buf; 232 int __len; 233 struct passwd **__res; 234 { 235 return (__posix_getpwnam_r(__cb, __pwd, __buf, __len, __res)); 236 } 237 238 #endif /* !__lint */ 239 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 240 241 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 242 243 extern struct passwd *getpwuid_r(); 244 extern struct passwd *getpwnam_r(); 245 246 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 247 248 #endif /* __STDC__ */ 249 250 #endif /* !defined(__XOPEN_OR_POSIX) || (_POSIX_C_SOURCE - 0 >= 199506L)... */ 251 252 #ifdef __cplusplus 253 } 254 #endif 255 256 #endif /* _PWD_H */ 257
