Changelog for the c-ares project
|
||||
|
||||
* May 16
|
||||
|
||||
- Added ares_getnameinfo which mimics the getnameinfo API (another feature
|
||||
that could use testing).
|
||||
|
||||
* May 14
|
||||
|
||||
- Added an inet_ntop function from BIND for systems that do not have it.

.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
|
||||
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 .
