For some of these * functions, the final POSIX 1003.1c standard had a different number of * arguments and return values. * * The following segment of this header provides support for the standard * interfaces while supporting applications written under earlier * releases. The application defines appropriate values of the feature * test macros _POSIX_C_SOURCE and _POSIX_PTHREAD_SEMANTICS to indicate * whether it was written to expect the Draft 6 or standard versions of * these interfaces, before including this header. This header then * provides a mapping from the source version of the interface to an * appropriate binary interface. Such mappings permit an application * to be built from libraries and objects which have mixed expectations * of the definitions of these functions. * * For applications using the Draft 6 definitions, the binary symbol is the * same as the source symbol, and no explicit mapping is needed. For the * standard interface, the function func() is mapped to the binary symbol * _posix_func(). The preferred mechanism for the remapping is a compiler * #pragma. If the compiler does not provide such a #pragma, the header file * defines a static function func() which calls the _posix_func() version; * this has to be done instead of #define since POSIX specifies that an * application can #undef the symbol and still be bound to the correct * implementation. Unfortunately, the statics confuse lint so we fallback to * #define in that case. * * NOTE: Support for the Draft 6 definitions is provided for compatibility * only. New applications/libraries should use the standard definitions. */ #if defined(__EXTENSIONS__) || !defined(__XOPEN_OR_POSIX) || \ (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) #if defined(__STDC__) #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) #ifdef __PRAGMA_REDEFINE_EXTNAME #pragma redefine_extname getgrgid_r __posix_getgrgid_r #pragma redefine_extname getgrnam_r __posix_getgrnam_r extern int getgrgid_r(gid_t, struct group *, char *, int, struct group **); extern int getgrnam_r(const char *, struct group *, char *, int, struct group **); #else /* __PRAGMA_REDEFINE_EXTNAME */ extern int __posix_getgrgid_r(gid_t, struct group *, char *, size_t, struct group **); extern int __posix_getgrnam_r(const char *, struct group *, char *, size_t, struct group **); #ifdef __lint #define getgrgid_r __posix_getgrgid_r #define getgrnam_r __posix_getgrnam_r #else /* !__lint */ static int getgrgid_r(gid_t __gid, struct group *__grp, char *__buf, int __len, struct group **__res) { return (__posix_getgrgid_r(__gid, __grp, __buf, __len, __res)); } static int getgrnam_r(const char *__cb, struct group *__grp, char *__buf, int __len, struct group **__res) { return (__posix_getgrnam_r(__cb, __grp, __buf, __len, __res)); } #endif /* !__lint */ #endif /* __PRAGMA_REDEFINE_EXTNAME */ #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ extern struct group *getgrgid_r(gid_t, struct group *, char *, int); extern struct group *getgrnam_r(const char *, struct group *, char *, int); #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ #else /* __STDC__ */ #if (_POSIX_C_SOURCE - 0 >= 199506L) || defined(_POSIX_PTHREAD_SEMANTICS) #ifdef __PRAGMA_REDEFINE_EXTNAME #pragma redefine_extname getgrgid_r __posix_getgrgid_r #pragma redefine_extname getgrnam_r __posix_getgrnam_r extern int getgrgid_r(); extern int getgrnam_r(); #else /* __PRAGMA_REDEFINE_EXTNAME */ extern int __posix_getgrgid_r(); extern int __posix_getgrnam_r(); #ifdef __lint #define getgrgid_r __posix_getgrgid_r #define getgrnam_r __posix_getgrnam_r #else /* !__lint */ static int getgrgid_r(__gid, __grp, __buf, __len, __res) gid_t __gid; struct group *__grp; char *__buf; int __len; struct group **__res; { return (__posix_getgrgid_r(__gid, __grp, __buf, __len, __res)); } static int getgrnam_r(__cb, __grp, __buf, __len, __res) char *__cb; struct group *__grp; char *__buf; int __len; struct group **__res; { return (__posix_getgrnam_r(__cb, __grp, __buf, __len, __res)); } #endif /* !__lint */ #endif /* __PRAGMA_REDEFINE_EXTNAME */ #else /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ extern struct group *getgrgid_r(); extern struct group *getgrnam_r(); #endif /* (_POSIX_C_SOURCE - 0 >= 199506L) || ... */ #endif /* __STDC__ */ #endif /* defined(__EXTENSIONS__) || !defined(__XOPEN_OR_POSIX)... */ #ifdef __cplusplus } #endif #endif /* _GRP_H */
