-.TH ARES_GETNAMEINFO 3 "1 May 2009"
-.SH NAME
-ares_getnameinfo \- Address-to-nodename translation in protocol-independent manner
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B typedef void (*ares_nameinfo_callback)(void *\fIarg\fP, int \fIstatus\fP,
-.B int \fItimeouts\fP, char *\fInode\fP, char *\fIservice\fP)
-.PP
-.B void ares_getnameinfo(ares_channel \fIchannel\fP, const struct sockaddr *\fIsa\fP,
-.B ares_socklen_t \fIsalen\fP, int \fIflags\fP, ares_nameinfo_callback \fIcallback\fP,
-.B void *\fIarg\fP)
-.fi
-.SH DESCRIPTION
-The
-.B ares_getnameinfo
-function is defined for protocol-independent address translation. The function
-is a combination of \fIares_gethostbyaddr(3)\fP and \fIgetservbyport(3)\fP. The function will
-translate the address either by executing a host query on the name service channel
-identified by
-.IR channel
-or it will attempt to resolve it locally if possible.
-The parameters
-.I sa
-and
-.I len
-give the address as a sockaddr structure, and
-.I flags
-gives the options that the function will use. Valid flags are listed below:
-.TP 19
-.B ARES_NI_NOFQDN
-Only the nodename portion of the FQDN is returned for local hosts.
-.TP 19
-.B ARES_NI_NUMERICHOST
-The numeric form of the hostname is returned rather than the name.
-.TP 19
-.B ARES_NI_NAMEREQD
-An error is returned if the hostname cannot be found in the DNS.
-.TP 19
-.B ARES_NI_NUMERICSERV
-The numeric form of the service is returned rather than the name.
-.TP 19
-.B ARES_NI_TCP
-The service name is to be looked up for the TCP protocol.
-.TP 19
-.B ARES_NI_UDP
-The service name is to be looked up for the UDP protocol.
-.TP 19
-.B ARES_NI_SCTP
-The service name is to be looked up for the SCTP protocol.
-.TP 19
-.B ARES_NI_DCCP
-The service name is to be looked up for the DCCP protocol.
-.TP 19
-.B ARES_NI_NUMERICSCOPE
-The numeric form of the scope ID is returned rather than the name.
-.TP 19
-.B ARES_NI_LOOKUPHOST
-A hostname lookup is being requested.
-.TP 19
-.B ARES_NI_LOOKUPSERVICE
-A service name lookup is being requested.
-.PP
-When the query
-is complete or has
-failed, the ares library will invoke \fIcallback\fP. Completion or failure of
-the query may happen immediately, or may happen during a later call to
-\fIares_process(3)\fP, \fIares_destroy(3)\fP or \fIares_cancel(3)\fP.
-.PP
-The callback argument
-.I arg
-is copied from the
-.B ares_getnameinfo
-argument
-.IR arg .
-The callback argument
-.I status
-indicates whether the query succeeded and, if not, how it failed. It
-may have any of the following values:
-.TP 19
-.B ARES_SUCCESS
-The host lookup completed successfully.
-.TP 19
-.B ARES_ENOTIMP
-The ares library does not know how to look up addresses of type
-.IR family .
-.TP 19
-.B ARES_ENOTFOUND
-The address
-.I addr
-was not found.
-.TP 19
-.B ARES_ENOMEM
-Memory was exhausted.
-.TP 19
-.B ARES_EDESTRUCTION
-The name service channel
-.I channel
-is being destroyed; the query will not be completed.
-.TP 19
-.B ARES_EBADFLAGS
-The
-.I flags
-parameter contains an illegal value.
-.PP
-The callback argument
-.I timeouts
-reports how many times a query timed out during the execution of the
-given request.
-.PP
-On successful completion of the query, the callback argument
-.I node
-contains a string representing the hostname (assuming
-.B ARES_NI_LOOKUPHOST
-was specified). Additionally,
-.I service
-contains a string representing the service name (assuming
-.B ARES_NI_LOOKUPSERVICE
-was specified).
-If the query did not complete successfully, or one of the values
-was not requested,
-.I node
-or
-.I service
-will be
-.BR NULL .
