-.nf
-    Since glibc 2.22:

-    glibc 2.21 and earlier:
-        _POSIX_C_SOURCE

-.SH DESCRIPTION
-The
-.BR getnameinfo ()
-function is the inverse of
-.BR getaddrinfo (3):
-it converts a socket address to a corresponding host and service,
-in a protocol-independent manner.
-It combines the functionality of
-.BR gethostbyaddr (3)
-and
-.BR getservbyport (3),
-but unlike those functions,
-.BR getnameinfo ()
-is reentrant and allows programs to eliminate
-IPv4-versus-IPv6 dependencies.
-.P
-The
-.I addr
-argument is a pointer to a generic socket address structure
-(of type
-.I sockaddr_in
-or
-.IR sockaddr_in6 )
-of size
-.I addrlen
-that holds the input IP address and port number.
-The arguments
-.I host
-and
-.I serv
-are pointers to caller-allocated buffers (of size
-.I hostlen
-and
-.I servlen
-respectively) into which
-.BR getnameinfo ()
-places null-terminated strings containing the host and
-service names respectively.
-.P
-The caller can specify that no hostname (or no service name)
-is required by providing a NULL
-.I host
-(or
-.IR serv )
-argument or a zero
-.I hostlen
-(or
-.IR servlen )
-argument.
-However, at least one of hostname or service name
-must be requested.
-.P
-The
-.I flags
-argument modifies the behavior of
-.BR getnameinfo ()
-as follows:
-.TP
-.B NI_NAMEREQD
-If set, then an error is returned if the hostname cannot be determined.
-.TP
-.B NI_DGRAM
-If set, then the service is datagram (UDP) based rather than
-stream (TCP) based.
-This is required for the few ports (512\[en]514)
-that have different services for UDP and TCP.
-.TP
-.B NI_NOFQDN
-If set, return only the hostname part of the fully qualified domain name
-for local hosts.
-.TP
-.B NI_NUMERICHOST
-If set, then the numeric form of the hostname is returned.
-.\" For example, by calling
-.\" .BR inet_ntop ()
-.\" instead of
-.\" .BR gethostbyaddr ().
-(When not set, this will still happen in case the node's name
-cannot be determined.)
-.\" POSIX.1-2001 TC1 has NI_NUMERICSCOPE, but glibc doesn't have it.
-.TP
-.B NI_NUMERICSERV
-If set, then the numeric form of the service address is returned.
-(When not set, this will still happen in case the service's name
-cannot be determined.)
-.SS Extensions to getnameinfo() for Internationalized Domain Names
-Starting with glibc 2.3.4,
-.BR getnameinfo ()
-has been extended to selectively allow
-hostnames to be transparently converted to and from the
-Internationalized Domain Name (IDN) format (see RFC 3490,
-.IR "Internationalizing Domain Names in Applications (IDNA)" ).
-Three new flags are defined:
-.TP
-.B NI_IDN
-If this flag is used, then the name found in the lookup process is
-converted from IDN format to the locale's encoding if necessary.
-ASCII-only names are not affected by the conversion, which
-makes this flag usable in existing programs and environments.
-.TP
-.B NI_IDN_ALLOW_UNASSIGNED
-.TQ
-.B NI_IDN_USE_STD3_ASCII_RULES
-Setting these flags will enable the
-IDNA_ALLOW_UNASSIGNED (allow unassigned Unicode code points) and
-IDNA_USE_STD3_ASCII_RULES (check output to make sure it is a STD3
-conforming hostname)
-flags respectively to be used in the IDNA handling.
-.SH RETURN VALUE
-.\" FIXME glibc defines the following additional errors, some which
-.\" can probably be returned by getnameinfo(); they need to
-.\" be documented.
-.\"
-.\"     #ifdef __USE_GNU
-.\"     #define EAI_INPROGRESS  -100  /* Processing request in progress.  */
-.\"     #define EAI_CANCELED    -101  /* Request canceled.  */
-.\"     #define EAI_NOTCANCELED -102  /* Request not canceled.  */
-.\"     #define EAI_ALLDONE     -103  /* All requests done.  */
-.\"     #define EAI_INTR        -104  /* Interrupted by a signal.  */
-.\"     #define EAI_IDN_ENCODE  -105  /* IDN encoding failed.  */
-.\"     #endif
-On success, 0 is returned, and node and service names, if requested,
-are filled with null-terminated strings, possibly truncated to fit
-the specified buffer lengths.
-On error, one of the following nonzero error codes is returned:
-.TP
-.B EAI_AGAIN
-The name could not be resolved at this time.
-Try again later.
-.TP
-.B EAI_BADFLAGS
-The
-.I flags
-argument has an invalid value.
-.TP
-.B EAI_FAIL
-A nonrecoverable error occurred.
-.TP
-.B EAI_FAMILY
-The address family was not recognized,
-or the address length was invalid for the specified family.
-.TP
-.B EAI_MEMORY
-Out of memory.
-.TP
-.B EAI_NONAME
-The name does not resolve for the supplied arguments.
-.B NI_NAMEREQD
-is set and the host's name cannot be located,
-or neither hostname nor service name were requested.
-.TP
-.B EAI_OVERFLOW
-The buffer pointed to by
-.I host
-or
-.I serv
-was too small.
-.TP
-.B EAI_SYSTEM
-A system error occurred.
-The error code can be found in
-.IR errno .
-.P
-The
-.BR gai_strerror (3)
-function translates these error codes to a human readable string,
-suitable for error reporting.

-.SH STANDARDS
-POSIX.1-2008.
-RFC\ 2553.
-.SH HISTORY
-glibc 2.1.
-POSIX.1-2001.
-.P
-Before glibc 2.2, the
-.I hostlen
-and
-.I servlen
-arguments were typed as
-.IR size_t .
-.SH NOTES
-In order to assist the programmer in choosing reasonable sizes
-for the supplied buffers,
-.I <netdb.h>
-defines the constants
-.P
-.in +4n
-.EX
-#define NI_MAXHOST      1025
-#define NI_MAXSERV      32
-.EE
-.in
-.P
-Since glibc 2.8,
-these definitions are exposed only if suitable
-feature test macros are defined, namely:
-.BR _GNU_SOURCE ,
-.B _DEFAULT_SOURCE
-(since glibc 2.19),
-or (in glibc versions up to and including 2.19)
-.B _BSD_SOURCE
-or
-.BR _SVID_SOURCE .
-.P
-The former is the constant
-.B MAXDNAME
-in recent versions of BIND's
-.I <arpa/nameser.h>
-header file.
-The latter is a guess based on the services listed
-in the current Assigned Numbers RFC.
-.SH EXAMPLES
-The following code tries to get the numeric hostname and service name,
-for a given socket address.
-Note that there is no hardcoded reference to
-a particular address family.
-.P
-.in +4n
-.EX
-struct sockaddr *addr;     /* input */
-socklen_t addrlen;         /* input */
-char hbuf[NI_MAXHOST], sbuf[NI_MAXSERV];
-\&
-if (getnameinfo(addr, addrlen, hbuf, sizeof(hbuf), sbuf,
-            sizeof(sbuf), NI_NUMERICHOST | NI_NUMERICSERV) == 0)
-    printf("host=%s, serv=%s\en", hbuf, sbuf);
-.EE
-.in
-.P
-The following version checks if the socket address has a
-reverse address mapping.
-.P
-.in +4n
-.EX
-struct sockaddr *addr;     /* input */
-socklen_t addrlen;         /* input */
-char hbuf[NI_MAXHOST];
-\&
-if (getnameinfo(addr, addrlen, hbuf, sizeof(hbuf),
-            NULL, 0, NI_NAMEREQD))
-    printf("could not resolve hostname");
-else
-    printf("host=%s\en", hbuf);
-.EE
-.in
-.P
-An example program using
-.BR getnameinfo ()
-can be found in
-.BR getaddrinfo (3).
