# This flag accepts an argument of the form current[:revision[:age]]. So,

# 1.
#
# If either revision or age are omitted, they default to 0. Also note that age
# must be less than or equal to the current interface number.
#
# Here are a set of rules to help you update your library version information:
#
# 1.Start with version information of 0:0:0 for each libtool library.
#
# 2.Update the version information only immediately before a public release of
# your software. More frequent updates are unnecessary, and only guarantee
# that the current interface number gets larger faster.
#
# 3.If the library source code has changed at all since the last update, then
# increment revision (c:r+1:a)
#
# 4.If any interfaces have been added, removed, or changed since the last
# update, increment current, and set revision to 0. (c+1:r=0:a)
#
# 5.If any interfaces have been added since the last public release, then
# increment age. (c:r:a+1)
#
# 6.If any interfaces have been removed since the last public release, then
# set age to 0. (c:r:a=0)

*
* IP-address/hostname to country converter.
*
* Problem; you want to know where IP a.b.c.d is located.
*
* Use ares_gethostbyname ("d.c.b.a.zz.countries.nerd.dk")
* and get the CNAME (host->h_name). Result will be:
* CNAME = zz<CC>.countries.nerd.dk with address 127.0.x.y (ver 1) or
* CNAME = <a.b.c.d>.zz.countries.nerd.dk with address 127.0.x.y (ver 2)
*
* The 2 letter country code is in <CC> and the ISO-3166 country
* number is in x.y (number = x*256 + y). Version 2 of the protocol is missing
* the <CC> number.

* File ares_build.h.dist is not included in the distribution archive.
* File ares_build.h is not present in the git tree.

* Right now you might be staring at file ares_build.h.in or ares_build.h,
* this is due to the following reason:
*
* On systems capable of running the configure script, the configure process
* will overwrite the distributed ares_build.h file with one that is suitable
* and specific to the library being configured and built, which is generated
* from the ares_build.h.in template file.

ares_cancel \- Cancel a resolve
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B void ares_cancel(ares_channel \fIchannel\fP)
.fi
.SH DESCRIPTION
The \fBares_cancel\fP function cancels all lookups/requests made on the the
name service channel identified by \fIchannel\fP. \fBares_cancel\fP invokes
the callbacks for each pending query on the channel, passing a status of
.BR ARES_ECANCELLED .
These calls give the callbacks a chance to clean up any state which
might have been stored in their arguments. If such a callback invocation adds
a new request to the channel, that request will \fInot\fP be cancelled by the
current invocation of \fBares_cancel\fP.

.TH ARES_CREATE_QUERY 3 "17 Aug 2012"
.SH NAME
ares_create_query \- Compose a single-question DNS query buffer
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_create_query(const char *\fIname\fP, int \fIdnsclass\fP,\
int \fItype\fP,
.B unsigned short \fIid\fP, int \fIrd\fP,\
unsigned char **\fIbuf\fP,
.B int *\fIbuflen\fP, int \fImax_udp_size\fP)
.fi
.SH DESCRIPTION
The
.B ares_create_query
function composes a DNS query with a single question.
The parameter
.I name
gives the query name as a NUL-terminated C string of period-separated
labels optionally ending with a period; periods and backslashes within
a label must be escaped with a backlash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
The parameter
.I id
gives a 16-bit identifier for the query. The parameter
.I rd
should be nonzero if recursion is desired, zero if not. The query
will be placed in an allocated buffer, a pointer to which will be
stored in the variable pointed to by
.IR buf ,
and the length of which will be stored in the variable pointed to by
.IR buflen .
It is the caller's responsibility to free this buffer using
\fIares_free_string(3)\fP when it is no longer needed.
The parameter
.I max_udp_size
should be nonzero to activate EDNS. Usage of \fIares_create_query(3)\fP\ with
.I max_udp_size
set to zero is equivalent to \fIares_mkquery(3)\fP.
.SH RETURN VALUES
.B ares_create_query
can return any of the following values:
.TP 15
.B ARES_SUCCESS
Construction of the DNS query succeeded.
.TP 15
.B ARES_EBADNAME
The query name
.I name
could not be encoded as a domain name, either because it contained a
zero-length label or because it contained a label of more than 63
characters.
.TP 15
.B ARES_ENOMEM
Memory was exhausted.

.SH DESCRIPTION
The \fBares_dup(3)\fP function duplicates an existing communications channel
for name service lookups. If it returns successfully, \fBares_dup(3)\fP will
set the variable pointed to by \fIdest\fP to a handle used to identify the
name service channel. The caller should invoke \fIares_destroy(3)\fP on the

.B long *\fIenclen\fP)
.fi
.SH DESCRIPTION
The
.B ares_expand_name
function converts a DNS-encoded domain name to a dot-separated C
string. The argument
.I encoded
gives the beginning of the encoded domain name, and the arguments
.I abuf
and
.I alen
give the containing message buffer (necessary for the processing of
indirection pointers within the encoded domain name). The result is
placed in a NUL-terminated allocated buffer, a pointer to which is
stored in the variable pointed to by
.IR s .
The length of the encoded name is stored in the variable pointed to by
.I enclen
so that the caller can advance past the encoded domain name to read
further data in the message.
Use \fIares_free_string(3)\fP to free the allocated hostname.
.SH RETURN VALUES
.B ares_expand_name
can return any of the following values:

.nf
.B #include <ares.h>
.PP
.B int ares_get_servers(ares_channel \fIchannel\fP, struct ares_addr_node **\fIservers\fP)
.fi
.SH DESCRIPTION
The \fBares_get_servers(3)\fP function retrieves name servers configuration
from the
channel data identified by
.IR channel ,
as a linked list of ares_addr_node structs storing a pointer to the first
node at the address specified by
.IR servers .
Function caller may traverse the returned name server linked list, or may use
it directly as suitable input for the \fBares_set_servers(3)\fP function, but
shall not shrink or extend the list on its own.
Each node of the name server linked list is stored in memory dynamically
allocated and managed by c-ares. It is the caller's responsibility to free
the resulting linked list, using \fBares_free_data(3)\fP , once the caller
does not need it any longer.
This function is capable of handling IPv4 and IPv6 name server
addresses simultaneously, rendering \fBares_save_options(3)\fP with
optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
IPv4-only name server usage.
.SH RETURN VALUES
.B ares_get_servers(3)
may return any of the following values:
.TP 15
.B ARES_SUCCESS
The name servers configuration was successfuly retrieved
.TP 15
.B ARES_ENOMEM

.TH ARES_GETHOSTBYADDR 3 "24 July 1998"
.SH NAME
ares_gethostbyaddr \- Initiate a host query by address
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_host_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B int \fItimeouts\fP, struct hostent *\fIhostent\fP)

.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_gethostbyaddr
function initiates a host query by address on the name service channel
identified by
.IR channel .
The parameters
.I addr
and
.I addrlen
give the address as a series of bytes, and
.I family
gives the type of address. 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_gethostbyaddr
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_ECANCELLED
The query was cancelled.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.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 hostent
points to a
.B struct hostent
containing the name of the host returned by the query. The callback
need not and should not attempt to free the memory pointed to by
.IR hostent ;
the ares library will free it when the callback returns. If the query
did not complete successfully,
.I hostent
will be
.BR NULL .

.TH ARES_GETHOSTBYNAME 3 "25 July 1998"
.SH NAME
ares_gethostbyname_file \- Lookup a name in the system's hosts file
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_gethostbyname_file(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIfamily\fP, struct hostent **host)
.fi
.SH DESCRIPTION
The
.B ares_gethostbyname_file
function performs a host lookup by name against the system's hosts file (or equivalent local hostname database).
The
.IR channel
parameter is required, but no asynchronous queries are performed. Instead, the
lookup is done via the same mechanism used to perform 'f' lookups
(see the
.I lookups
options field in \fIares_init_options(3)\fP).
The parameter
.I name
gives the hostname as a NUL-terminated C string, and
.I family
gives the desired type of address for the resulting host entry.
.PP
The return value 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 and
.I host
now points to the result (and must be freed with \fIares_free_hostent(3)\fP).
.TP 19
.B ARES_ENOTFOUND
The hostname
.I name
was not found.
.TP 19
.B ARES_EFILE
There was a file I/O error while performing the lookup.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.PP
On successful completion of the query, the pointer pointed to by
.I host
points to a
.B struct hostent
containing the address of the host returned by the lookup. The user must
free the memory pointed to by
.IR host
when finished with it by calling \fIares_free_hostent(3)\fP. If the lookup did
not complete successfully,
.I host
will be
.BR NULL .

.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_ECANCELLED
The query was cancelled.
.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 .

.B #include <ares.h>
.PP
.B int ares_getsock(ares_channel \fIchannel\fP, ares_socket_t *\fIsocks\fP,
.B int \fInumsocks\fP);
.fi
.SH DESCRIPTION
The
.B ares_getsock
function retrieves the set of socket descriptors which the calling
application should wait on for reading and/or writing for the
processing of name service queries pending on the name service channel
identified by
.IR channel .
Socket descriptors will be set in the socket descriptor array pointed to by
\fIsocks\fP.
\fInumsocks\fP is the size of the given array in number of ints.
This function can only return information about up to 16 sockets. If more are
in use (however unlikely that is), they are simply not reported back.
.SH RETURN VALUES
\fBares_getsock\fP returns a bitmask for what actions to wait for on the
different sockets. The ares.h header file provides these convenience macros to
extract the information appropriately:
.nf
#define ARES_GETSOCK_MAXNUM 16 /* ares_getsock() can return info about
this many sockets */
#define ARES_GETSOCK_READABLE(bits,num) (bits & (1<< (num)))
#define ARES_GETSOCK_WRITABLE(bits,num) (bits & (1 << ((num) + \
ARES_GETSOCK_MAXNUM)))

.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_init(ares_channel *\fIchannelptr\fP)
.B int ares_init_options(ares_channel *\fIchannelptr\fP,
.B struct ares_options *\fIoptions\fP, int \fIoptmask\fP)
.PP
.B cc file.c -lcares
.fi
.SH DESCRIPTION
The \fBares_init\fP function initializes a communications channel for name
service lookups. If it returns successfully, \fBares_init\fP will set the
variable pointed to by \fIchannelptr\fP to a handle used to identify the name
service channel. The caller should invoke
.BR ares_destroy (3)
on the handle when the channel is no longer needed.
.PP
The \fBares_init_options\fP function also initializes a name service channel,
with additional options useful for applications requiring more control over
name service configuration. The \fIoptmask\fP parameter specifies which fields
in the structure pointed to by \fIoptions\fP are set, as follows:
.TP 18
.B ARES_OPT_FLAGS
.B int \fIflags\fP;
.br
Flags controlling the behavior of the resolver. See below for a
description of possible flag values.
.TP 18
.B ARES_OPT_TIMEOUT
.B int \fItimeout\fP;
.br
The number of seconds each name server is given to respond to a query on the
first try. (After the first try, the timeout algorithm becomes more
complicated, but scales linearly with the value of \fItimeout\fP.) The
default is five seconds. This option is being deprecated by
\fIARES_OPT_TIMEOUTMS\fP starting in c-ares 1.5.2.
.TP 18
.B ARES_OPT_TIMEOUTMS
.B int \fItimeout\fP;
.br
The number of milliseconds each name server is given to respond to a query on
the first try. (After the first try, the timeout algorithm becomes more
complicated, but scales linearly with the value of \fItimeout\fP.) The
default is five seconds. Note that this option is specified with the same
struct field as the former \fIARES_OPT_TIMEOUT\fP, it is but the option bits
that tell c-ares how to interpret the number. This option was added in c-ares
1.5.2.
.TP 18
.B ARES_OPT_TRIES
.B int \fItries\fP;
.br
The number of tries the resolver will try contacting each name server
before giving up. The default is four tries.
.TP 18
.B ARES_OPT_NDOTS
.B int \fIndots\fP;
.br
The number of dots which must be present in a domain name for it to be
queried for "as is" prior to querying for it with the default domain
extensions appended. The default value is 1 unless set otherwise by
resolv.conf or the RES_OPTIONS environment variable.
.TP 18
.B ARES_OPT_PORT
.B unsigned short \fIport\fP;
.br
The port to use for queries (both TCP and UDP), in network byte order.
The default value is 53 (in network byte order), the standard name
service port.
.TP 18
.B ARES_OPT_SERVERS
.B struct in_addr *\fIservers\fP;
.br
.B int \fInservers\fP;
.br
The list of IPv4 servers to contact, instead of the servers specified in
resolv.conf or the local named. In order to allow specification of either
IPv4 or IPv6 name servers, the
.BR ares_set_servers(3)
function must be used instead.
.TP 18
.B ARES_OPT_DOMAINS
.B char **\fIdomains\fP;
.br
.B int \fIndomains\fP;
.br
The domains to search, instead of the domains specified in resolv.conf
or the domain derived from the kernel hostname variable.
.TP 18
.B ARES_OPT_LOOKUPS
.B char *\fIlookups\fP;
.br
The lookups to perform for host queries.
.I lookups
should be set to a string of the characters "b" or "f", where "b"
indicates a DNS lookup and "f" indicates a lookup in the hosts file.
.TP 18
.B ARES_OPT_SOCK_STATE_CB
.B void (*\fIsock_state_cb\fP)(void *data, int s, int read, int write);
.br
.B void *\fIsock_state_cb_data\fP;
.br
A callback function to be invoked when a socket changes state.
.I s
will be passed the socket whose state has changed;
.I read
will be set to true if the socket should listen for read events, and
.I write
will be set to true if the socket should listen for write events.
The value of
.I sock_state_cb_data
will be passed as the
.I data
argument.
.PP
The
.I flags
field should be the bitwise or of some subset of the following values:
.TP 23
.B ARES_FLAG_USEVC
Always use TCP queries (the "virtual circuit") instead of UDP
queries. Normally, TCP is only used if a UDP query yields a truncated
result.
.TP 23
.B ARES_FLAG_PRIMARY
Only query the first server in the list of servers to query.

If a truncated response to a UDP query is received, do not fall back
to TCP; simply continue on with the truncated response.
.TP 23
.B ARES_FLAG_NORECURSE
Do not set the "recursion desired" bit on outgoing queries, so that the name
server being contacted will not try to fetch the answer from other servers if
it doesn't know the answer locally. Be aware that ares will not do the
recursion for you. Recursion must be handled by the application calling ares
if \fIARES_FLAG_NORECURSE\fP is set.

.B ARES_FLAG_STAYOPEN
Do not close communications sockets when the number of active queries
drops to zero.
.TP 23
.B ARES_FLAG_NOSEARCH
Do not use the default search domains; only query hostnames as-is or
as aliases.
.TP 23
.B ARES_FLAG_NOALIASES
Do not honor the HOSTALIASES environment variable, which normally
specifies a file of hostname translations.
.TP 23
.B ARES_FLAG_NOCHECKRESP
Do not discard responses with the SERVFAIL, NOTIMP, or REFUSED
response code or responses whose questions don't match the questions
in the request. Primarily useful for writing clients which might be
used to test or debug name servers.

.TH ARES_LIBRARY_CLEANUP 3 "19 May 2009"
.SH NAME
ares_library_cleanup \- c-ares library deinitialization
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B void ares_library_cleanup(void)
.PP
.B cc file.c -lcares
.fi
.SH DESCRIPTION
.PP
The
.B ares_library_cleanup
function uninitializes the c-ares library, freeing all resources
previously acquired by \fIares_library_init(3)\fP when the library
was initialized, provided there was only one single previous call to
\fIares_library_init(3)\fP. If there was more than one previous call to
\fIares_library_init(3)\fP, this function uninitializes the c-ares
library only if it is the call matching the call to
\fIares_library_init(3)\fP which initialized the library
(usually the very first call to \fIares_library_init(3)\fP).
Other calls to \fIares_library_cleanup(3)\fP have no effect other than
decrementing an internal counter.
.PP
This function must be called when the program using c-ares will
no longer need any c-ares function. Once the program has called
\fIares_library_cleanup(3)\fP sufficiently often such that the
library is uninitialised, it shall not make any further call to any
c-ares function.
.PP
This function does not cancel any pending c-ares lookups or requests
previously done. Program must use \fIares_cancel(3)\fP for this purpose.
.PP
.B This function is not thread safe.
You have to call it once the program is about to terminate, but this call must
be done once the program has terminated every single thread that it could have
initiated. This is required to avoid potential race conditions in library
deinitialization, and also due to the fact that \fIares_library_cleanup(3)\fP
might call functions from other libraries that are thread unsafe, and could
conflict with any other thread that is already using these other libraries.
.PP
Win32/64 application DLLs shall not call \fIares_library_cleanup(3)\fP from
the DllMain function. Doing so will produce deadlocks and other problems.
.SH AVAILABILITY
This function was first introduced in c-ares version 1.7.0 along with the
definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_CLEANUP\fP as an
indication of the availability of this function. Reference counting in
\fIares_library_init()\fP and \fIares_library_cleanup()\fP, which requires
calls to the former function to match calls to the latter, is present since
c-ares version 1.10.0.
Earlier versions would deinitialize the library on the first call
to \fIares_library_cleanup()\fP.
.PP
Since the introduction of this function, it is absolutely mandatory to call it
for any Win32/64 program using c-ares.
.PP
Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
\fIares_library_cleanup(3)\fP due to the fact that \fIcurrently\fP it is nearly
a do-nothing function on non-Win32/64 platforms.

.TH ARES_LIBRARY_INIT 3 "19 May 2009"
.SH NAME
ares_library_init \- c-ares library initialization
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_library_init(int \fIflags\fP)
.PP
.B cc file.c -lcares
.fi
.SH DESCRIPTION
.PP
The
.B ares_library_init
function performs initializations internally required by the c-ares
library that must take place before any other function provided by
c-ares can be used in a program.
.PP
This function must be called at least once within the life of a program,
before the program actually executes any other c-ares library function.
Initializations done by this function remain effective until a number of
calls to \fIares_library_cleanup(3)\fP equal to the number of calls to
this function are performed.
.PP
Successive calls to this function do nothing further, only the first
call done when c-ares is in an uninitialized state is actually
effective.
.PP
The
.I flags
parameter is a bit pattern that tells c-ares exactly which features
should be initialized, as described below. Set the desired bits by
ORing the values together. In normal operation you should specify
\fIARES_LIB_INIT_ALL\fP. Don't use any other value unless you are
familiar with it and trying to control some internal c-ares feature.
.PP
.B This function is not thread safe.
You have to call it once the program has started, but this call must be done
before the program starts any other thread. This is required to avoid
potential race conditions in library initialization, and also due to the fact
that \fIares_library_init(3)\fP might call functions from other libraries that
are thread unsafe, and could conflict with any other thread that is already
using these other libraries.
.PP
Win32/64 application DLLs shall not call \fIares_library_init(3)\fP from the
DllMain function. Doing so will produce deadlocks and other problems.
.SH FLAGS
.TP 5
.B ARES_LIB_INIT_ALL
Initialize everything possible. This sets all known bits.
.TP
.B ARES_LIB_INIT_WIN32
Initialize Win32/64 specific libraries.
.TP
.B ARES_LIB_INIT_NONE
Initialize nothing extra. This sets no bit.
.SH RETURN VALUE
Upon successful completion, ares_library_init() will return 0. Otherwise, a
non-zero error number will be returned to indicate the error. Except for
\fIares_strerror(3)\fP, you shall not call any other c-ares function upon
\fIares_library_init(3)\fP failure.
.SH AVAILABILITY
This function was first introduced in c-ares version 1.7.0 along with the
definition of preprocessor symbol \fICARES_HAVE_ARES_LIBRARY_INIT\fP as an
indication of the availability of this function. Its recursive behavior,
which requires a matching number of calls to \fIares_library_cleanup()\fP
in order to deinitialize the library, is present since c-ares version
1.10.0. Earlier versions would deinitialize the library on the first call
to \fIares_library_cleanup()\fP.
.PP
Since the introduction of this function it is absolutely mandatory to
call it for any Win32/64 program using c-ares.
.PP
Non-Win32/64 systems can still use c-ares version 1.7.0 without calling
\fIares_library_init(3)\fP due to the fact that \fIcurrently\fP it is nearly
a do-nothing function on non-Win32/64 platforms at this point.

.TH ARES_MKQUERY 3 "20 Nov 2009"
.SH NAME
ares_mkquery \- Compose a single-question DNS query buffer
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_mkquery(const char *\fIname\fP, int \fIdnsclass\fP, int \fItype\fP,
.B unsigned short \fIid\fP, int \fIrd\fP, unsigned char **\fIbuf\fP,
.B int *\fIbuflen\fP)
.fi
.SH DESCRIPTION
Deprecated function. See \fIares_create_query(3)\fP instead!
The
.B ares_mkquery
function composes a DNS query with a single question.
The parameter
.I name
gives the query name as a NUL-terminated C string of period-separated
labels optionally ending with a period; periods and backslashes within
a label must be escaped with a backlash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
The parameter
.I id
gives a 16-bit identifier for the query. The parameter
.I rd
should be nonzero if recursion is desired, zero if not. The query
will be placed in an allocated buffer, a pointer to which will be
stored in the variable pointed to by
.IR buf ,
and the length of which will be stored in the variable pointed to by
.IR buflen .
It is the caller's responsibility to free this buffer using
\fIares_free_string(3)\fP when it is no longer needed.
Usage of \fIares_mkquery(3)\fP is deprecated, whereas the function is
equivalent to \fIares_create_query(3)\fP with \fBmax_udp_size\fP set to
0.
.SH RETURN VALUES
.B ares_mkquery
can return any of the following values:
.TP 15
.B ARES_SUCCESS
Construction of the DNS query succeeded.
.TP 15
.B ARES_EBADNAME
The query name
.I name
could not be encoded as a domain name, either because it contained a
zero-length label or because it contained a label of more than 63
characters.
.TP 15
.B ARES_ENOMEM
Memory was exhausted.

.TH ARES_PARSE_PTR_REPLY 3 "25 July 1998"
.SH NAME
ares_parse_ptr_reply \- Parse a reply to a DNS query of type PTR into a hostent
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_parse_ptr_reply(const unsigned char *\fIabuf\fP, int \fIalen\fP,
.B const void *\fIaddr\fP, int \fIaddrlen\fP, int \fIfamily\fP,
.B struct hostent **\fIhost\fP);
.fi
.SH DESCRIPTION
The
.B ares_parse_ptr_reply
function parses the response to a query of type PTR into a
.BR "struct hostent" .
The parameters
.I abuf
and
.I alen
give the contents of the response. The parameters
.IR addr ,
.IR addrlen ,
and
.I family
specify which address was queried for; they are not used to verify the
response, merely used to fill in the address of the
.BR "struct hostent" .
The resulting
.B struct hostent
is stored in allocated memory and a pointer to it stored into the
variable pointed to by
.IR host .
It is the caller's responsibility to free the resulting host structure
using
.BR ares_free_hostent (3)
when it is no longer needed.
.SH RETURN VALUES
.B ares_parse_ptr_reply
can return any of the following values:
.TP 15
.B ARES_SUCCESS
The response was successfully parsed.
.TP 15
.B ARES_EBADRESP
The response was malformatted.
.TP 15
.B ARES_ENODATA
The response did not contain an answer to the query.

.TH ARES_PROCESS 3 "25 July 1998"
.SH NAME
ares_process \- Process events for name resolution
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B void ares_process(ares_channel \fIchannel\fP, fd_set *\fIread_fds\fP,
.B fd_set *\fIwrite_fds\fP)
.fi
.PP
.B void ares_process_fd(ares_channel \fIchannel\fP,
.B ares_socket_t \fIread_fd\fP,
.B ares_socket_t \fIwrite_fd\fP)
.fi
.SH DESCRIPTION
The \fBares_process(3)\fP function handles input/output events and timeouts
associated with queries pending on the name service channel identified by
.IR channel .
The file descriptor sets pointed to by \fIread_fds\fP and \fIwrite_fds\fP
should have file descriptors set in them according to whether the file
descriptors specified by \fIares_fds(3)\fP are ready for reading and writing.
(The easiest way to determine this information is to invoke
.B select
with a timeout no greater than the timeout given by \fIares_timeout(3)\fP ).
.PP
The
.B ares_process
function will invoke callbacks for pending queries if they complete
successfully or fail.
\fBares_process_fd(3)\fP works the same way but acts and operates only on the
specific file descriptors (sockets) you pass in to the function. Use
ARES_SOCKET_BAD for "no action". This function is of course provided to allow
users of c-ares to void select() in their applications and within c-ares.
.SS EXAMPLE
The following code fragment waits for all pending queries on a channel
to complete:
.PP
.RS
.nf
int nfds, count;
fd_set readers, writers;
struct timeval tv, *tvp;
while (1)
{
FD_ZERO(&readers);
FD_ZERO(&writers);
nfds = ares_fds(channel, &readers, &writers);
if (nfds == 0)
break;
tvp = ares_timeout(channel, NULL, &tv);
count = select(nfds, &readers, &writers, NULL, tvp);
ares_process(channel, &readers, &writers);
}

.TH ARES_QUERY 3 "24 July 1998"
.SH NAME
ares_query \- Initiate a single-question DNS query
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_query(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_query
function initiates a single-question DNS query on the name service
channel identified by
.IR channel .
The parameter
.I name
gives the query name as a NUL-terminated C string of period-separated
labels optionally ending with a period; periods and backslashes within
a label must be escaped with a backslash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
When the query is complete or has failed, the ares library will invoke
.IR callback .
Completion or failure of the query may happen immediately, or may
happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_query
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 query completed successfully.
.TP 19
.B ARES_ENODATA
The query completed but contains no answers.
.TP 19
.B ARES_EFORMERR
The query completed but the server claims that the query was
malformatted.
.TP 19
.B ARES_ESERVFAIL
The query completed but the server claims to have experienced a
failure. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_ENOTFOUND
The query completed but the queried-for domain name was not found.
.TP 19
.B ARES_ENOTIMP
The query completed but the server does not implement the operation
requested by the query. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EREFUSED
The query completed but the server refused the query. (This code can
only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EBADNAME
The query name
.I name
could not be encoded as a domain name, either because it contained a
zero-length label or because it contained a label of more than 63
characters.
.TP 19
.B ARES_ETIMEOUT
No name servers responded within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_ECANCELLED
The query was cancelled.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
The callback argument
.I timeouts
reports how many times a query timed out during the execution of the
given request.
.PP
If the query completed (even if there was something wrong with it, as
indicated by some of the above error codes), the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete,
.I abuf
will be NULL and
.I alen
will be 0.

.TH ARES_SAVE_OPTIONS 3 "5 March 2010"
.SH NAME
ares_save_options \- Save configuration values obtained from initialized ares_channel
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_save_options(ares_channel \fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP)
.fi
.SH DESCRIPTION
The \fBares_save_options(3)\fP function saves the channel data identified by
.IR channel ,
into the options struct identified by
.IR options ,
and saves the mask of options which are set to the integer
pointer (passed by reference) identified by
.IR optmask .
The resultant options and optmask are then able to be
passed directly to ares_init_options. When the options
are no longer needed, ares_destroy_options should be called
to free any associated memory.
.SH RETURN VALUES
.B ares_save_options(3)
can return any of the following values:
.TP 15
.B ARES_SUCCESS
The channel data was successfuly stored
.TP 15
.B ARES_ENOMEM
The memory was exhausted
.TP 15
.B ARES_ENODATA
The channel data identified by
.IR channel
were invalid.
.SH NOTE
Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it
won't be extended to cover new functions. This function will remain
functioning, but it can only return config data that can be represented in
this config struct, which may no longer be the complete set of config
options. \fBares_dup(3)\fP will not have that restriction.
The ares_options struct can not handle potential IPv6 name servers the
ares_channel might be configured to use. The \fBares_save_options(3)\fP function
will only return IPv4 servers, if any. In order to retrieve all name servers
an ares_channel might be using, the \fBares_get_servers(3)\fP function must be
used instead.

.TH ARES_SEARCH 3 "24 July 1998"
.SH NAME
ares_search \- Initiate a DNS query with domain search
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_search(ares_channel \fIchannel\fP, const char *\fIname\fP,
.B int \fIdnsclass\fP, int \fItype\fP, ares_callback \fIcallback\fP,
.B void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_search
function initiates a series of single-question DNS queries on the name
service channel identified by
.IR channel ,
using the channel's search domains as well as a host alias file given
by the HOSTALIAS environment variable. The parameter
.I name
gives the alias name or the base of the query name as a NUL-terminated
C string of period-separated labels; if it ends with a period, the
channel's search domains will not be used. Periods and backslashes
within a label must be escaped with a backslash. The parameters
.I dnsclass
and
.I type
give the class and type of the query using the values defined in
.BR <arpa/nameser.h> .
When the query sequence is complete or has failed, the ares library
will invoke
.IR callback .
Completion or failure of the query sequence may happen immediately, or
may happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_search
argument
.IR arg .
The callback argument
.I status
indicates whether the query sequence ended with a successful query
and, if not, how the query sequence failed. It may have any of the
following values:
.TP 19
.B ARES_SUCCESS
A query completed successfully.
.TP 19
.B ARES_ENODATA
No query completed successfully; when the query was tried without a
search domain appended, a response was returned with no answers.
.TP 19
.B ARES_EFORMERR
A query completed but the server claimed that the query was
malformatted.
.TP 19
.B ARES_ESERVFAIL
No query completed successfully; when the query was tried without a
search domain appended, the server claimed to have experienced a
failure. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_ENOTFOUND
No query completed successfully; when the query was tried without a
search domain appended, the server reported that the queried-for
domain name was not found.
.TP 19
.B ARES_ENOTIMP
A query completed but the server does not implement the operation
requested by the query. (This code can only occur if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_EREFUSED
A query completed but the server refused the query. (This code can
only occur returned if the
.B ARES_FLAG_NOCHECKRESP
flag was specified at channel initialization time; otherwise, such
responses are ignored at the
.BR ares_send (3)
level.)
.TP 19
.B ARES_TIMEOUT
No name servers responded to a query within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_ECANCELLED
The query was cancelled.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
The callback argument
.I timeouts
reports how many times a query timed out during the execution of the
given request.
.PP
If a query completed successfully, the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete successfully,
.I abuf
will usually be NULL and
.I alen
will usually be 0, but in some cases an unsuccessful query result may
be placed in
.IR abuf .

.TH ARES_SEND 3 "25 July 1998"
.SH NAME
ares_send \- Initiate a DNS query
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B typedef void (*ares_callback)(void *\fIarg\fP, int \fIstatus\fP,
.B int \fItimeouts\fP, unsigned char *\fIabuf\fP, int \fIalen\fP)
.PP
.B void ares_send(ares_channel \fIchannel\fP, const unsigned char *\fIqbuf\fP,
.B int \fIqlen\fP, ares_callback \fIcallback\fP, void *\fIarg\fP)
.fi
.SH DESCRIPTION
The
.B ares_send
function initiates a DNS query on the name service channel identified
by
.IR channel .
The parameters
.I qbuf
and
.I qlen
give the DNS query, which should already have been formatted according
to the DNS protocol. When the query is complete or has failed, the
ares library will invoke
.IR callback .
Completion or failure of the query may happen immediately, or may
happen during a later call to
.BR ares_process (3)
or
.BR ares_destroy (3).
.PP
The callback argument
.I arg
is copied from the
.B ares_send
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 query completed.
.TP 19
.B ARES_EBADQUERY
The query buffer was poorly formed (was not long enough for a DNS
header or was too long for TCP transmission).
.TP 19
.B ARES_ETIMEOUT
No name servers responded within the timeout period.
.TP 19
.B ARES_ECONNREFUSED
No name servers could be contacted.
.TP 19
.B ARES_ENOMEM
Memory was exhausted.
.TP 19
.B ARES_ECANCELLED
The query was cancelled.
.TP 19
.B ARES_EDESTRUCTION
The name service channel
.I channel
is being destroyed; the query will not be completed.
.PP
The callback argument
.I timeouts
reports how many times a query timed out during the execution of the
given request.
.PP
If the query completed, the callback argument
.I abuf
points to a result buffer of length
.IR alen .
If the query did not complete,
.I abuf
will be NULL and
.I alen
will be 0.
.PP
Unless the flag
.B ARES_FLAG_NOCHECKRESP
was set at channel initialization time,
.B ares_send
will normally ignore responses whose questions do not match the
questions in
.IR qbuf ,
as well as responses with reply codes of
.BR SERVFAIL ,
.BR NOTIMP ,
and
.BR REFUSED .
Unlike other query functions in the ares library, however,
.B ares_send
does not inspect the header of the reply packet to determine the error
status, so a callback status of
.B ARES_SUCCESS
does not reflect as much about the response as for other query
functions.

.TH ARES_SET_SERVERS 3 "5 March 2010"
.SH NAME
ares_set_servers \- Initialize an ares_channel name servers configuration
.SH SYNOPSIS
.nf
.B #include <ares.h>
.PP
.B int ares_set_servers(ares_channel \fIchannel\fP, struct ares_addr_node *\fIservers\fP)
.fi
.SH DESCRIPTION
The \fBares_set_servers(3)\fP function initializes name servers configuration
for the channel data identified by
.IR channel ,
from a
.IR servers
pointer to a linked list of ares_addr_node structs holding name servers
address data.
The name server linked list pointer argument may be the result of a previous
call to \fBares_get_servers(3)\fP or a linked list of ares_addr_node structs
setup by other means.
This function replaces any potentially previously configured name servers
with the ones given in the linked list. So, in order to configure a channel
with more than one name server all the desired ones must be specified in a
single list.
\fBares_set_servers(3)\fP does not take ownership of the linked list argument.
The caller is responsible for freeing the linked list when no longer needed.
This function is capable of handling IPv4 and IPv6 name server
addresses simultaneously, rendering \fBares_init_options(3)\fP with
optmask \fBARES_OPT_SERVERS\fP functionally obsolete except for
IPv4-only name server usage.
.SH RETURN VALUES
.B ares_set_servers(3)
may return any of the following values:
.TP 15
.B ARES_SUCCESS
The name servers configuration was successfuly initialized.
.TP 15
.B ARES_ENOMEM
The process's available memory was exhausted.
.TP 15
.B ARES_ENODATA
The channel data identified by
.IR channel
was invalid.
.TP 15
.B ARES_ENOTINITIALIZED
c-ares library initialization not yet performed.

.PP
.B struct timeval *ares_timeout(ares_channel \fIchannel\fP,
.B struct timeval *\fImaxtv\fP, struct timeval *\fItv\fP)
.fi
.SH DESCRIPTION
The
.B ares_timeout
function determines the maximum time for which the caller should wait before
invoking \fIares_process(3)\fP to process timeouts. The parameter
.I maxtv
specifies a existing maximum timeout, or
.B NULL
if the caller does not wish to apply a maximum timeout. The parameter
.I tv
must point to a writable buffer of type
.BR "struct timeval" .
It is valid for
.I maxtv
and
.I tv
to have the same value.
.PP
If no queries have timeouts pending sooner than the given maximum
timeout,
.B ares_timeout
returns the value of
.IR maxtv;
otherwise
.B ares_timeout
stores the appropriate timeout value into the buffer pointed to by
.I tv
and returns the value of
.IR tv .

## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
