addrinfo **res" +.Ft void +.Fn freeaddrinfo "struct addrinfo *ai" +.Ft "char *" +.Fn gai_strerror "int ecode" +.\" +.Sh DESCRIPTION +The +.Fn getaddrinfo +function is defined for protocol-independent nodename-to-address translation. +It performs the functionality of +.Xr gethostbyname 3 +and +.Xr getservbyname 3 , +but in a more sophisticated manner. +.Pp +The +.Li addrinfo +structure is defined as a result of including the +.Aq Pa netdb.h +header: +.Bd -literal -offset +struct addrinfo { + int ai_flags; /* AI_PASSIVE, AI_CANONNAME, AI_NUMERICHOST */ + int ai_family; /* PF_xxx */ + int ai_socktype; /* SOCK_xxx */ + int ai_protocol; /* 0 or IPPROTO_xxx for IPv4 and IPv6 */ + size_t ai_addrlen; /* length of ai_addr */ + char *ai_canonname; /* canonical name for nodename */ + struct sockaddr *ai_addr; /* binary address */ + struct addrinfo *ai_next; /* next structure in linked list */ +}; +.Ed +.Pp +The +.Fa nodename +and +.Fa servname +arguments are pointers to null-terminated strings or +.Dv NULL . +One or both of these two arguments must be a +.Pf non Dv -NULL +pointer. +In the normal client scenario, both the +.Fa nodename +and +.Fa servname +are specified. +In the normal server scenario, only the +.Fa servname +is specified. +A +.Pf non Dv -NULL +.Fa nodename +string can be either a node name or a numeric host address string +(i.e., a dotted-decimal IPv4 address or an IPv6 hex address). +A +.Pf non Dv -NULL +.Fa servname +string can be either a service name or a decimal port number. +.Pp +The caller can optionally pass an +.Li addrinfo +structure, pointed to by the third argument, +to provide hints concerning the type of socket that the caller supports. +In this +.Fa hints +structure all members other than +.Fa ai_flags , +.Fa ai_family , +.Fa ai_socktype , +and +.Fa ai_protocol +must be zero or a +.Dv NULL +pointer. +A value of +.Dv PF_UNSPEC +for +.Fa ai_family +means the caller will accept any protocol family. +A value of 0 for +.Fa ai_socktype +means the caller will accept any socket type. +A value of 0 for +.Fa ai_protocol +means the caller will accept any protocol. +For example, if the caller handles only TCP and not UDP, then the +.Fa ai_socktype +member of the hints structure should be set to +.Dv SOCK_STREAM +when +.Fn getaddrinfo +is called. +If the caller handles only IPv4 and not IPv6, then the +.Fa ai_family +member of the +.Fa hints +structure should be set to +.Dv PF_INET +when +.Fn getaddrinfo +is called. +If the third argument to +.Fn getaddrinfo +is a +.Dv NULL +pointer, this is the same as if the caller had filled in an +.Li addrinfo +structure initialized to zero with +.Fa ai_family +set to +.Dv PF_UNSPEC . +.Pp +Upon successful return a pointer to a linked list of one or more +.Li addrinfo +structures is returned through the final argument. +The caller can process each +.Li addrinfo +structure in this list by following the +.Fa ai_next +pointer, until a +.Dv NULL +pointer is encountered. +In each returned +.Li addrinfo +structure the three members +.Fa ai_family , +.Fa ai_socktype , +and +.Fa ai_protocol +are the corresponding arguments for a call to the +.Fn socket +function. +In each +.Li addrinfo +structure the +.Fa ai_addr +member points to a filled-in socket address structure whose length is +specified by the +.Fa ai_addrlen +member. +.Pp +If the +.Dv AI_PASSIVE +bit is set in the +.Fa ai_flags +member of the +.Fa hints +structure, then the caller plans to use the returned socket address +structure in a call to +.Fn bind . +In this case, if the +.Fa nodename +argument is a +.Dv NULL +pointer, then the IP address portion of the socket +address structure will be set to +.Dv INADDR_ANY +for an IPv4 address or +.Dv IN6ADDR_ANY_INIT +for an IPv6 address. +.Pp +If the +.Dv AI_PASSIVE +bit is not set in the +.Fa ai_flags +member of the +.Fa hints +structure, then the returned socket address structure will be ready for a +call to +.Fn connect +(for a connection-oriented protocol) +or either +.Fn connect , +.Fn sendto , +or +.Fn sendmsg +(for a connectionless protocol). +In this case, if the +.Fa nodename +argument is a +.Dv NULL +pointer, then the IP address portion of the +socket address structure will be set to the loopback address. +.Pp +If the +.Dv AI_CANONNAME +bit is set in the +.Fa ai_flags +member of the +.Fa hints +structure, then upon successful return the +.Fa ai_canonname +member of the first +.Li addrinfo +structure in the linked list will point to a null-terminated string +containing the canonical name of the specified +.Fa nodename . +.Pp +If the +.Dv AI_NUMERICHOST +bit is set in the +.Fa ai_flags +member of the +.Fa hints +structure, then a +.Pf non Dv -NULL +.Fa nodename +string must be a numeric host address string. +Otherwise an error of +.Dv EAI_NONAME +is returned. +This flag prevents any type of name resolution service (e.g., the DNS) +from being called. +.Pp +The arguments to +.Fn getaddrinfo +must be sufficiently consistent and unambiguous. +Here are some problem cases you may encounter: +.Bl -bullet +.It +.Fn getaddrinfo +will fail if the members in the +.Fa hints +structure are not consistent. +For example, for internet address families, +.Fn getaddrinfo +will fail if you specify +.Dv SOCK_STREAM +to +.Fa ai_socktype +while you specify +.Dv IPPROTO_UDP +to +.Fa ai_protocol . +.It +If you specify a +.Fa servname +which is defined only for certain +.Fa ai_socktype , +.Fn getaddrinfo +will fail because the arguments are not consistent. +For example, +.Fn getaddrinfo +will return an error if you ask for +.Dq Li tftp +service on +.Dv SOCK_STREAM . +.It +For internet address families, if you specify +.Fa servname +while you set +.Fa ai_socktype +to +.Dv SOCK_RAW , +.Fn getaddrinfo +will fail, because service names are not defined for the internet +.Dv SOCK_RAW +space. +.It +If you specify numeric +.Fa servname , +while leaving +.Fa ai_socktype +and +.Fa ai_protocol +unspecified, +.Fn getaddrinfo +will fail. +This is because the numeric +.Fa servname +does not identify any socket type, and +.Fn getaddrinfo +is not allowed to glob the argument in such case. +.El +.Pp +All of the information returned by +.Fn getaddrinfo +is dynamically allocated: +the +.Li addrinfo +structures, the socket address structures, and canonical node name +strings pointed to by the addrinfo structures. +To return this information to the system the function +.Fn freeaddrinfo +is called. +The +.Fa addrinfo +structure pointed to by the +.Fa ai argument +is freed, along with any dynamic storage pointed to by the structure. +This operation is repeated until a +.Dv NULL +.Fa ai_next +pointer is encountered. +.Pp +To aid applications in printing error messages based on the +.Dv EAI_xxx +codes returned by +.Fn getaddrinfo , +.Fn gai_strerror +is defined. +The argument is one of the +.Dv EAI_xxx +values defined earlier and the return value points to a string describing +the error. +If the argument is not one of the +.Dv EAI_xxx +values, the function still returns a pointer to a string whose contents +indicate an unknown error. +.\" +.Sh EXTENSIONS +This implementation supports numeric IPv6 address notation with the +experimental scope identifier. +By appending a percent sign and scope identifier to the address, you +can specify the value of the +.Li sin6_scope_id +field of the socket address. +This makes management of scoped address easier, +and allows cut-and-paste input of scoped addresses. +.Pp +At the moment the code supports only link-local addresses in this format. +The scope identifier is hardcoded to name of hardware interface associated +with the link, +(such as +.Li ne0 ) . +For example, +.Dq Li fe80::1%ne0 , +which means +.Do +.Li fe80::1 +on the link associated with the +.Li ne0 +interface +.Dc . +.Pp +This implementation is still very experimental and non-standard. +The current implementation assumes a one-to-one relationship between +interfaces and links, which is not necessarily true according to the +specification. +.\" +.Sh EXAMPLES +The following code tries to connect to +.Dq Li www.kame.net +service +.Dq Li http . +via stream socket. +It loops through all the addresses available, regardless of the address family. +If the destination resolves to an IPv4 address, it will use an +.Dv AF_INET +socket. +Similarly, if it resolves to IPv6, an +.Dv AF_INET6 +socket is used. +Observe that there is no hardcoded reference to particular address family. +The code works even if +.Fn getaddrinfo +returns addresses that are not IPv4/v6. +.Bd -literal
