-.Sh DESCRIPTION
-.Fn Getipnodebyname ,
-and
-.Fn getipnodebyaddr
-each return a pointer to a
-.Ft hostent
-structure (see below) describing an internet host
-referenced by name or by address, as the function names indicate.
-This structure contains either the information obtained from the name server,
-.Xr @INDOT@named @SYS_OPS_EXT@ ,
-or broken-out fields from a line in
-.Pa /etc/hosts .
-If the local name server is not running, these routines do a lookup in
-.Pa /etc/hosts .
-.Bd -literal -offset indent
-struct hostent {
- char *h_name; /* official name of host */
- char **h_aliases; /* alias list */
- int h_addrtype; /* host address type */
- int h_length; /* length of address */
- char **h_addr_list; /* list of addresses from name server */
-};
-
-#define h_addr h_addr_list[0] /* address, for backward compatibility */
-.Ed
-.Pp
-The members of this structure are:
-.Bl -tag -width "h_addr_list"
-.It h_name
-Official name of the host.
-.It h_aliases
-A zero-terminated array of alternate names for the host.
-.It h_addrtype
-The type of address being returned.
-.It h_length
-The length, in bytes, of the address.
-.It h_addr_list
-A zero-terminated array of network addresses for the host.
-Host addresses are returned in network byte order.
-.It h_addr
-The first address in
-.Li h_addr_list ;
-this is for backward compatibility.
-.El
-.Pp
-This structure should be freed after use by calling
-.Fn freehostent .
-.Pp
-When using the nameserver,
-.Fn getiphostbyaddr
-will search for the named host in each parent domain given in the
-.Dq Li search
-directive of
-.Xr resolv.conf @FORMAT_EXT@
-unless the name contains a dot
-.Pq Dq \&. .
-If the name contains no dot, and if the environment variable
-.Ev HOSTALIASES
-contains the name of an alias file, the alias file will first be searched
-for an alias matching the input name.
-See
-.Xr hostname @DESC_EXT@
-for the domain search procedure and the alias file format.
-.Pp
-.Fn Getiphostbyaddr
-can be told to look for IPv4 addresses, IPv6 addresses or both IPv4 and IPv6.
-If IPv4 addresses only are to be looked up then
-.Fa af
-should be set to
-.Dv AF_INET ,
-otherwise it should be set to
-.Dv AF_INET6 .
-.Pp
-There are three flags that can be set
-.Bl -tag -width "AI_ADDRCONFIG"
-.It Dv AI_V4MAPPED
-Return IPv4 addresses if no IPv6 addresses are found.
-This flag is ignored unless
-.Fa af
-is
-.Dv AF_INET6 .
-.It Dv AI_ALL
-Return IPv4 addresses as well IPv6 addresses if
-.Dv AI_V4MAPPED
-is set.
-This flag is ignored unless
-.Fa af
-is
-.Dv AF_INET6 .
-.It Dv AI_ADDRCONFIG
-Only return addresses of a given type if the system has an active interface
-with that type.
-.El
-.Pp
-Also
-.Dv AI_DEFAULT
-is defined to be
-.Dv (AI_V4MAPPED|AI_ADDRCONFIG) .
-.Pp
-.Fn Getipnodebyaddr
-will lookup IPv4 mapped and compatible addresses in the IPv4 name
-space and IPv6 name space
-.Pp
-.Fn Freehostent
-frees the hostent structure allocated be
-.Fn getipnodebyname
-and
-.Fn getipnodebyaddr .
-The structures returned by
-.Fn gethostbyname ,
-.Fn gethostbyname2 ,
-.Fn gethostbyaddr
-and
-.Fn gethostent
-should not be passed to
-.Fn freehostent
-as they are pointers to static areas.
-.Sh ENVIRONMENT
-.Bl -tag -width "HOSTALIASES " -compact
-.It Ev HOSTALIASES
-Name of file containing
-.Pq Ar host alias , full hostname
-pairs.
-.El
-.Sh FILES
-.Bl -tag -width "HOSTALIASES " -compact
-.It Pa /etc/hosts
-See
-.Xr hosts @FORMAT_EXT@ .
-.El
-.Sh DIAGNOSTICS
-.Pp
-Error return status from
-.Fn getipnodebyname
-and
-.Fn getipnodebyaddr
-is indicated by return of a null pointer.
-In this case
-.Ft error
-may then be checked to see whether this is a temporary failure
-or an invalid or unknown host.
-.Ft errno
-can have the following values:
-.Bl -tag -width "HOST_NOT_FOUND " -offset indent
-.It Dv NETDB_INTERNAL
-This indicates an internal error in the library, unrelated to the network
-or name service.
-.Ft errno
-will be valid in this case; see
-.Xr perror @SYSCALL_EXT@ .
-.It Dv HOST_NOT_FOUND
-No such host is known.
-.It Dv TRY_AGAIN
-This is usually a temporary error
-and means that the local server did not receive
-a response from an authoritative server.
-A retry at some later time may succeed.
-.It Dv NO_RECOVERY
-Some unexpected server failure was encountered.
-This is a non-recoverable error, as one might expect.
-.It Dv NO_ADDRESS
-The requested name is valid but does not have an IP address;
-this is not a temporary error.
-This means that the name is known to the name server but there is no address
-associated with this name.
-Another type of request to the name server using this domain name
-will result in an answer;
-for example, a mail-forwarder may be registered for this domain.
