/*------------------------------------------------------------------------- * * getaddrinfo.h * Support getaddrinfo() on platforms that don't have it. * * Note: we use our own routines on platforms that don't HAVE_STRUCT_ADDRINFO, * whether or not the library routine getaddrinfo() can be found. This * policy is needed because on some platforms a manually installed libbind.a * may provide getaddrinfo(), yet the system headers may not provide the * struct definitions needed to call it. To avoid conflict with the libbind * definition in such cases, we rename our routines to pg_xxx() via macros. * * This code will also work on platforms where struct addrinfo is defined * in the system headers but no getaddrinfo() can be located. * * Copyright (c) 2003-2012, PostgreSQL Global Development Group * * src/include/getaddrinfo.h * *------------------------------------------------------------------------- */ #ifndef GETADDRINFO_H #define GETADDRINFO_H #include <sys/socket.h> #include <netdb.h> /* Various macros that ought to be in <netdb.h>, but might not be */ #ifndef EAI_FAIL #ifndef WIN32 #define EAI_BADFLAGS (-1) #define EAI_NONAME (-2) #define EAI_AGAIN (-3) #define EAI_FAIL (-4) #define EAI_FAMILY (-6) #define EAI_SOCKTYPE (-7) #define EAI_SERVICE (-8) #define EAI_MEMORY (-10) #define EAI_SYSTEM (-11) #else /* WIN32 */ #ifdef WIN32_ONLY_COMPILER #ifndef WSA_NOT_ENOUGH_MEMORY #define WSA_NOT_ENOUGH_MEMORY (WSAENOBUFS) #endif #ifndef __BORLANDC__ #define WSATYPE_NOT_FOUND (WSABASEERR+109) #endif #endif #define EAI_AGAIN WSATRY_AGAIN #define EAI_BADFLAGS WSAEINVAL #define EAI_FAIL WSANO_RECOVERY #define EAI_FAMILY WSAEAFNOSUPPORT #define EAI_MEMORY WSA_NOT_ENOUGH_MEMORY #define EAI_NODATA WSANO_DATA #define EAI_NONAME WSAHOST_NOT_FOUND #define EAI_SERVICE WSATYPE_NOT_FOUND #define EAI_SOCKTYPE WSAESOCKTNOSUPPORT #endif /* !WIN32 */ #endif /* !EAI_FAIL */ #ifndef AI_PASSIVE #define AI_PASSIVE 0x0001 #endif #ifndef AI_NUMERICHOST /* * some platforms don't support AI_NUMERICHOST; define as zero if using * the system version of getaddrinfo... */ #if defined(HAVE_STRUCT_ADDRINFO) && defined(HAVE_GETADDRINFO) #define AI_NUMERICHOST 0 #else #define AI_NUMERICHOST 0x0004 #endif #endif #ifndef NI_NUMERICHOST #define NI_NUMERICHOST 1 #endif #ifndef NI_NUMERICSERV #define NI_NUMERICSERV 2 #endif #ifndef NI_NAMEREQD #define NI_NAMEREQD 4 #endif #ifndef NI_MAXHOST #define NI_MAXHOST 1025 #endif #ifndef NI_MAXSERV #define NI_MAXSERV 32 #endif #ifndef HAVE_STRUCT_ADDRINFO #ifndef WIN32 struct addrinfo { int ai_flags; int ai_family; int ai_socktype; int ai_protocol; size_t ai_addrlen; struct sockaddr *ai_addr; char *ai_canonname; struct addrinfo *ai_next; }; #else /* * The order of the structure elements on Win32 doesn't match the * order specified in the standard, but we have to match it for * IPv6 to work. */ struct addrinfo { int ai_flags; int ai_family; int ai_socktype; int ai_protocol; size_t ai_addrlen; char *ai_canonname; struct sockaddr *ai_addr; struct addrinfo *ai_next; }; #endif #endif /* HAVE_STRUCT_ADDRINFO */ #ifndef HAVE_GETADDRINFO /* Rename private copies per comments above */ #ifdef getaddrinfo #undef getaddrinfo #endif #define getaddrinfo pg_getaddrinfo #ifdef freeaddrinfo #undef freeaddrinfo #endif #define freeaddrinfo pg_freeaddrinfo #ifdef gai_strerror #undef gai_strerror #endif #define gai_strerror pg_gai_strerror #ifdef getnameinfo #undef getnameinfo #endif #define getnameinfo pg_getnameinfo extern int getaddrinfo(const char *node, const char *service, const struct addrinfo * hints, struct addrinfo ** res); extern void freeaddrinfo(struct addrinfo * res); extern const char *gai_strerror(int errcode); extern int getnameinfo(const struct sockaddr * sa, int salen, char *node, int nodelen, char *service, int servicelen, int flags); #endif /* HAVE_GETADDRINFO */ #endif /* GETADDRINFO_H */
