For some of these 104 * functions, the final POSIX 1003.1c standard had a different number of 105 * arguments and return values. 106 * 107 * The following segment of this header provides support for the standard 108 * interfaces while supporting applications written under earlier 109 * releases. The application defines appropriate values of the feature 110 * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate 111 * whether it was written to expect the Draft 6 or standard versions of 112 * these interfaces, before including this header. This header then 113 * provides a mapping from the source version of the interface to an 114 * appropriate binary interface. Such mappings permit an application 115 * to be built from libraries and objects which have mixed expectations 116 * of the definitions of these functions. 117 * 118 * For applications using the Draft 6 definitions, the binary symbol is the 119 * same as the source symbol, and no explicit mapping is needed. For the 120 * standard interface, the function func() is mapped to the binary symbol 121 * _posix_func(). The preferred mechanism for the remapping is a compiler 122 * #pragma. If the compiler does not provide such a #pragma, the header file 123 * defines a static function func() which calls the _posix_func() version; 124 * this has to be done instead of #define since POSIX specifies that an 125 * application can #undef the symbol and still be bound to the correct 126 * implementation. Unfortunately, the statics confuse lint so we fallback to 127 * #define in that case. 128 * 129 * NOTE: Support for the Draft 6 definitions is provided for compatibility 130 * only. New applications/libraries should use the standard definitions. 131 */ 132 133 #if defined(__EXTENSIONS__) || !defined(__XOPEN_OR_POSIX) || \ 134 (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 135 136 #if defined(__STDC__) 137 138 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 139 140 #ifdef __PRAGMA_REDEFINE_EXTNAME 141 #pragma redefine_extname getgrgid_r __posix_getgrgid_r 142 #pragma redefine_extname getgrnam_r __posix_getgrnam_r 143 extern int getgrgid_r(gid_t, struct group *, char *, int, struct group **); 144 extern int getgrnam_r(const char *, struct group *, char *, int, 145 struct group **); 146 #else /* __PRAGMA_REDEFINE_EXTNAME */ 147 148 extern int __posix_getgrgid_r(gid_t, struct group *, char *, size_t, 149 struct group **); 150 extern int __posix_getgrnam_r(const char *, struct group *, char *, size_t, 151 struct group **); 152 153 #ifdef __lint 154 155 #define getgrgid_r __posix_getgrgid_r 156 #define getgrnam_r __posix_getgrnam_r 157 158 #else /* !__lint */ 159 160 static int 161 getgrgid_r(gid_t __gid, struct group *__grp, char *__buf, int __len, 162 struct group **__res) 163 { 164 return (__posix_getgrgid_r(__gid, __grp, __buf, __len, __res)); 165 } 166 static int 167 getgrnam_r(const char *__cb, struct group *__grp, char *__buf, int __len, 168 struct group **__res) 169 { 170 return (__posix_getgrnam_r(__cb, __grp, __buf, __len, __res)); 171 } 172 173 #endif /* !__lint */ 174 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 175 176 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 177 178 extern struct group *getgrgid_r(gid_t, struct group *, char *, int); 179 extern struct group *getgrnam_r(const char *, struct group *, char *, int); 180 181 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 182 183 #else /* __STDC__ */ 184 185 #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) 186 187 #ifdef __PRAGMA_REDEFINE_EXTNAME 188 #pragma redefine_extname getgrgid_r __posix_getgrgid_r 189 #pragma redefine_extname getgrnam_r __posix_getgrnam_r 190 extern int getgrgid_r(); 191 extern int getgrnam_r(); 192 #else /* __PRAGMA_REDEFINE_EXTNAME */ 193 194 extern int __posix_getgrgid_r(); 195 extern int __posix_getgrnam_r(); 196 197 #ifdef __lint 198 199 #define getgrgid_r __posix_getgrgid_r 200 #define getgrnam_r __posix_getgrnam_r 201 202 #else /* !__lint */ 203 204 static int 205 getgrgid_r(__gid, __grp, __buf, __len, __res) 206 gid_t __gid; 207 struct group *__grp; 208 char *__buf; 209 int __len; 210 struct group **__res; 211 { 212 return (__posix_getgrgid_r(__gid, __grp, __buf, __len, __res)); 213 } 214 static int 215 getgrnam_r(__cb, __grp, __buf, __len, __res) 216 char *__cb; 217 struct group *__grp; 218 char *__buf; 219 int __len; 220 struct group **__res; 221 { 222 return (__posix_getgrnam_r(__cb, __grp, __buf, __len, __res)); 223 } 224 225 #endif /* !__lint */ 226 #endif /* __PRAGMA_REDEFINE_EXTNAME */ 227 228 #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 229 230 extern struct group *getgrgid_r(); 231 extern struct group *getgrnam_r(); 232 233 #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ 234 235 #endif /* __STDC__ */ 236 237 #endif /* defined(__EXTENSIONS__) || !defined(__XOPEN_OR_POSIX)... */ 238 239 #ifdef __cplusplus 240 } 241 #endif 242 243 #endif /* _GRP_H */ 244
