+.TH "LWRES_GETNAMEINFO" "3" "Jun 30, 2000" "BIND9" ""
+.SH NAME
+lwres_getnameinfo \- lightweight resolver socket address structure to hostname and service name
+.SH SYNOPSIS
+\fB#include <lwres/netdb.h>
+.sp
+.na
+int
+lwres_getnameinfo(const struct sockaddr *sa, size_t salen, char *host, size_t hostlen, char *serv, size_t servlen, int flags);
+.ad
+\fR.SH "DESCRIPTION"
+.PP
+This function is equivalent to the \fBgetnameinfo\fR(3) function defined in RFC2133.
+\fBlwres_getnameinfo()\fR returns the hostname for the
+\fBstruct sockaddr\fR \fIsa\fR which is
+\fIsalen\fR bytes long. The hostname is of length
+\fIhostlen\fR and is returned via
+\fI*host.\fR The maximum length of the hostname is
+1025 bytes: NI_MAXHOST.
+.PP
+The name of the service associated with the port number in
+\fIsa\fR is returned in \fI*serv.\fR
+It is \fIservlen\fR bytes long. The maximum length
+of the service name is NI_MAXSERV - 32 bytes.
+.PP
+The \fIflags\fR argument sets the following
+bits:
+.TP
+\fBNI_NOFQDN\fR
+A fully qualified domain name is not required for local hosts.
+The local part of the fully qualified domain name is returned instead.
+.TP
+\fBNI_NUMERICHOST\fR
+Return the address in numeric form, as if calling inet_ntop(),
+instead of a host name.
+.TP
+\fBNI_NAMEREQD\fR
+A name is required. If the hostname cannot be found in the DNS and
+this flag is set, a non-zero error code is returned.
+If the hostname is not found and the flag is not set, the 
+address is returned in numeric form.
+.TP
+\fBNI_NUMERICSERV\fR
+The service name is returned as a digit string representing the port number.
+.TP
+\fBNI_DGRAM\fR
+Specifies that the service being looked up is a datagram
+service, and causes getservbyport() to be called with a second
+argument of "udp" instead of its default of "tcp". This is required
+for the few ports (512-514) that have different services for UDP and
+TCP.
+.SH "RETURN VALUES"
+.PP
+\fBlwres_getnameinfo()\fR
+returns 0 on success or a non-zero error code if an error occurs.
+.SH "SEE ALSO"
+.PP
+\fBRFC2133\fR,
+\fBgetservbyport\fR(3),
+\fBlwres\fR(3),
+\fBlwres_getnameinfo\fR(3),
+\fBlwres_getnamebyaddr\fR(3).
+\fBlwres_net_ntop\fR(3).
+.SH "BUGS"
+.PP
+RFC2133 fails to define what the nonzero return values of
+\fBgetnameinfo\fR(3)
+are.
