-.TH ARES_CREATE_QUERY 3 "17 Aug 2012"
-.SH NAME
-ares_create_query \- Compose a single-question DNS query buffer
-.SH SYNOPSIS
-.nf
-#include <ares.h>
-
-int ares_create_query(const char *\fIname\fP,
-                      int \fIdnsclass\fP,
-                      int \fItype\fP,
-                      unsigned short \fIid\fP,

-                      int \fImax_udp_size\fP)
-.fi
-.SH DESCRIPTION
-The \fIares_create_query(3)\fP function composes a DNS query with a single
-question.  The parameter \fIname\fP 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 \fIdnsclass\fP and \fItype\fP give the class and type of the
-query using the values defined in \fB<arpa/nameser.h>\fP.
-
-The parameter \fIid\fP gives a 16-bit identifier for the query.
-
-The parameter \fIrd\fP 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 \fIbuf\fP, and the length of which will
-be stored in the variable pointed to by \fIbuflen\fP.
-
-It is the caller's responsibility to free this buffer using
-\fIares_free_string(3)\fP when it is no longer needed.  The parameter
-\fImax_udp_size\fP should be nonzero to activate EDNS. Usage of
-\fIares_create_query(3)\fP\ with \fImax_udp_size\fP set to zero is equivalent
-to using \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_ENOTFOUND
-The query name
-.I name
-refers to a
-.I .onion
-domain name. See RFC 7686.
-.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 NAME
-ares_expand_name \- Expand a DNS-encoded domain name
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_expand_name(const unsigned char *\fIencoded\fP,
-.B      const unsigned char *\fIabuf\fP, int \fIalen\fP, char **\fIs\fP,
-.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:
-.TP 15
-.B ARES_SUCCESS
-Expansion of the encoded name succeeded.
-.TP 15
-.B ARES_EBADNAME
-The encoded domain name was malformed and could not be expanded.

-.B int ares_get_servers(ares_channel \fIchannel\fP, struct ares_addr_node **\fIservers\fP)
-.B int ares_get_servers_ports(ares_channel \fIchannel\fP, struct ares_addr_port_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 .
-
-The \fBares_get_servers_ports(3)\fP function also retrieves any per-server
-port information that may have been previously configured, returning a linked
-list of ares_addr_port structures.
-
-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 /
-\fBares_set_servers_ports(3)\fP functions, 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
-This function may return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The name servers configuration was successfully retrieved
-.TP 15
-.B ARES_ENOMEM
-The memory was exhausted
-.TP 15
-.B ARES_ENODATA

-.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 .

-.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 .

-.fi
-.SH DESCRIPTION
-The \fBares_init_options(3)\fP function initializes a communications channel
-for name service lookups.  If it returns successfully,
-\fBares_init_options(3)\fP will set the variable pointed to by
-\fIchannelptr\fP to a handle used to identify the name service channel.  The
-caller should invoke \fIares_destroy(3)\fP on the handle when the channel is
-no longer needed.
-
-The \fIoptmask\fP parameter generally 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_UDP_PORT
-.B unsigned short \fIudp_port\fP;
-.br
-The port to use for queries over UDP, in network byte order.
-The default value is 53 (in network byte order), the standard name
-service port.
-.TP 18
-.B ARES_OPT_TCP_PORT
-.B unsigned short \fItcp_port\fP;
-.br
-The port to use for queries over TCP, 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, ares_socket_t socket_fd, int readable, int writable);
-.br
-.B void *\fIsock_state_cb_data\fP;
-.br
-A callback function to be invoked when a socket changes state.
-.I socket_fd
-will be passed the socket whose state has changed;
-.I readable
-will be set to true if the socket should listen for read events, and
-.I writable
-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.
-.TP 18
-.B ARES_OPT_SORTLIST
-.B struct apattern *\fIsortlist\fP;
-.br
-.B int \fInsort\fP;
-.br
-A list of IP address ranges that specifies the order of preference that
-results from \fIares_gethostbyname\fP should be returned in.  Note that
-this can only be used with a sortlist retrieved via
-\fBares_save_options(3)\fP (because
-.B struct apattern
-is opaque); to set a fresh sort list, use \fBares_set_sortlist(3)\fP.
-.TP 18
-.B ARES_OPT_SOCK_SNDBUF
-.B int \fIsocket_send_buffer_size\fP;
-.br
-The send buffer size to set for the socket.
-.TP 18
-.B ARES_OPT_SOCK_RCVBUF
-.B int \fIsocket_receive_buffer_size\fP;
-.br
-The receive buffer size to set for the socket.
-.TP 18
-.B ARES_OPT_EDNSPSZ
-.B int \fIednspsz\fP;
-.br
-The message size to be advertized in EDNS; only takes effect if the
-.B ARES_FLAG_EDNS
-flag is set.
-.TP 18
-.B ARES_OPT_RESOLVCONF
-.B char *\fIresolvconf_path\fP;
-.br
-The path to use for reading the resolv.conf file. The
-.I resolvconf_path
-should be set to a path string, and will be honoured on *nix like systems. The
-default is
-.B /etc/resolv.conf
-.br
-.PP
-The \fIoptmask\fP parameter also includes options without a corresponding
-field in the
-.B ares_options
-structure, as follows:
-.TP 23
-.B ARES_OPT_ROTATE
-Perform round-robin selection of the nameservers configured for the channel
-for each resolution.
-.TP 23
-.B ARES_OPT_NOROTATE
-Do not perform round-robin nameserver selection; always use the list of
-nameservers in the same order.
-.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.
-.TP 23
-.B ARES_FLAG_IGNTC
-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.
-.TP 23
-.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.
-.TP 23
-.B ARES_FLAG_EDNS
-Include an EDNS pseudo-resource record (RFC 2671) in generated requests.
-.SH RETURN VALUES
-\fBares_init_options(3)\fP can return any of the following values:
-.TP 14
-.B ARES_SUCCESS
-Initialization succeeded.
-.TP 14
-.B ARES_EFILE
-A configuration file could not be read.
-.TP 14
-.B ARES_ENOMEM
-The process's available memory was exhausted.
-.TP 14
-.B ARES_ENOTINITIALIZED
-c-ares library initialization not yet performed.
-.SH NOTES
-When initializing from
-.B /etc/resolv.conf,
-(or, alternatively when specified by the
-.I resolvconf_path
-path location)
-\fBares_init_options(3)\fP reads the \fIdomain\fP and \fIsearch\fP directives
-to allow lookups of short names relative to the domains specified. The
-\fIdomain\fP and \fIsearch\fP directives override one another. If more that
-one instance of either \fIdomain\fP or \fIsearch\fP directives is specified,
-the last occurrence wins. For more information, please see the
-.BR resolv.conf (5)
-manual page.

-.TH ARES_LIBRARY_CLEANUP 3 "19 May 2009"
-.SH NAME
-ares_library_cleanup \- c-ares library deinitialization
-.SH SYNOPSIS
-.nf
-#include <ares.h>
-
-void ares_library_cleanup(void)
-.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.

-.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
-The
-.B ares_library_init_mem
-function allows the caller to provide memory management functions that the
-c-ares library will be use instead of \fImalloc(3)\fP, \fIfree(3)\fP and
-\fIrealloc(3)\fP.
-.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
-On Windows platforms, the library user should ensure that \fIWSAStartup()\fP
-is called before the c-ares library is initialized and used.
-.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_LIBRARY_INIT_ANDROID 3 "13 Sept 2017"
-.SH NAME
-ares_library_init_android \- c-ares library Android initialization
-.SH SYNOPSIS
-.nf
-#include <ares.h>
-
-int ares_library_init_android(jobject \fIconnectivity_manager\fP)
-
-int ares_library_android_initialized();
-
-void ares_library_init_jvm(JavaVM *\fIjvm\fP)
-
-.fi
-.SH DESCRIPTION
-The \fIares_library_init_android(3)\fP function performs initializations
-internally required by the c-ares library when used on Android. This can take
-place anytime after \fIares_library_init(3)\fP. It must take place after
-\fIares_library_init_jvm\fP. ares_library_init_android must be called before
-DNS resolution will work on Android 8 (Oreo) or newer when targetSdkVersion is
-set to 26+.
-
-As of Android 8 (API level 26) getting DNS server information has
-becomei more restrictive and can only be accessed using the
-Connectivity Manager. It is necessary to pass the connectivity
-manager to c-ares via JNI. Also, the ACCESS_NETWORK_STATE permission
-must be present in the Android application.
-
-Android older than 8 do not need to to be initialized as they
-are less restrictive. However, this is a run time not compile time
-limitation. Proper Android initialization should take place regardless
-of the targeted Android version.
-
-Deinitialization will take place though \fIares_library_cleanup(3)\fP.
-
-The \fBares_library_init_jvm\fP function allows the caller to register the JVM
-with c-ares.  It's meant to be called during JNI_OnLoad because you're
-guaranteed to have the JVM in that function. The JVM is required in order to
-use the Connectivty Manager registered using
-\fIares_library_init_android(3)\fP. This must be call before
-\fIares_library_init_android(3)\fP.
-
-The \fBares_library_android_initialized\fP function can be used to check
-whether c-ares has been initialized for use with Android.
-.SH RETURN VALUES
-ARES_SUCCESS will be returned on success otherwise an error code will be
-returned.
-.SH THREAD SAFETY
-.B These init functions are 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
-these might call functions from other libraries that
-are thread unsafe, and could conflict with any other thread that is already
-using these other libraries.
-.SH JNI
-Accessing the Connectivity Manager though Java:
-
-Register the \fIares_library_android_init\fP.
-.nf
-  static JNINativeMethod funcs[] = {
-  { "initialize_native",     "(Landroid/net/ConnectivityManager;)I",
-    (void *)&ares_library_init_android}
-  };
-
-  JNIEXPORT jint JNICALL JNI_OnLoad(JavaVM *vm, void *reserved)
-  {
-    JNIEnv *env = NULL;
-    jclass  cls = NULL;
-    jint    res;
-  
-    if ((*vm)->GetEnv(vm, (void **)&env, JNI_VERSION_1_6) != JNI_OK)

-.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_ENOTFOUND
-The query name
-.I name
-refers to a
-.I .onion
-domain name. See RFC 7686.
-.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_PROCESS 3 "25 July 1998"
-.SH NAME
-ares_process \- Process events for name resolution
-.SH SYNOPSIS
-.nf
-#include <ares.h>
-
-void ares_process(ares_channel \fIchannel\fP,
-                  fd_set *\fIread_fds\fP,
-                  fd_set *\fIwrite_fds\fP)
-
-void ares_process_fd(ares_channel \fIchannel\fP,
-                     ares_socket_t \fIread_fd\fP,
-                     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 \fBselect(3)\fP
-with a timeout no greater than the timeout given by \fIares_timeout(3)\fP).
-
-The \fBares_process(3)\fP 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 provided to allow users of
-c-ares to void \fIselect(3)\fP in their applications and within c-ares.
-
-To only process possible timeout conditions without a socket event occurring,
-one may pass NULL as the values for both \fIread_fds\fP and \fIwrite_fds\fP for
-\fBares_process(3)\fP, or ARES_SOCKET_BAD for both \fIread_fd\fP and
-\fIwrite_fd\fP for \fBares_process_fd(3)\fP.
-.SH EXAMPLE
-The following code fragment waits for all pending queries on a channel
-to complete:
-
-.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);
-}

-.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.

-
-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

-.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.

-.B void ares_set_local_dev(ares_channel \fIchannel\fP, const char* \fIlocal_dev_name\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_set_local_dev\fP function causes all future sockets
-to be bound to this device with SO_BINDTODEVICE.  This forces communications
-to go over a certain interface, which can be useful on multi-homed machines.
-This option is only supported on Linux, and root privileges are required

-.TH ARES_SET_SERVERS 3 "5 March 2010"
-.SH NAME
-ares_set_servers, ares_set_servers_ports \- Initialize an ares_channel name servers configuration
-.SH SYNOPSIS

-.B #include <ares.h>
-.PP
-.B int ares_set_servers(ares_channel \fIchannel\fP, struct ares_addr_node *\fIservers\fP)
-.B int ares_set_servers_ports(ares_channel \fIchannel\fP, struct ares_addr_port_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.
-.PP
-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 \fBares_addr_node\fP structs
-set up by other means.
-.PP
-The \fBares_set_servers(3)\fP function also allows the specification of UDP and
-TCP ports to be used for communication on a per-server basis.  The provided
-linked list argument may be the result of a previous call to
-\fBares_get_servers_ports(3)\fP or a linked list of \fBares_addr_port_node\fP structs
-set up by other means.
-.PP
-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.
-.PP
-The function does not take ownership of the linked list argument.
-The caller is responsible for freeing the linked list when no longer needed.
-.PP
-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

-
-.fi
-.SH DESCRIPTION
-.PP
-This function sets a set of callback \fIfunctions\fP in the given ares channel handle.
-These callback functions will be invoked to create/destroy socket objects and perform
-io, instead of the normal system calls. A client application can override normal network
-operation fully through this functionality, and provide its own transport layer.
-.PP
-All callback functions are expected to operate like their system equivalents, and to
-set
-.BR errno(3)
-to an appropriate error code on failure. C-ares also expects all io functions to behave
-asynchronously, i.e. as if the socket object has been set to non-blocking mode. Thus
-read/write calls (for TCP connections) are expected to often generate
-.BR EAGAIN
-or
-.BR EWOULDBLOCK.
-
-.PP
-The \fIuser_data\fP value is provided to each callback function invocation to serve as
-context.
-.PP
-The
-.B ares_socket_functions
-must provide the following callbacks:
-.TP 18
-.B \fIasocket\fP
-.B ares_socket_t(*)(int \fIdomain\fP, int \fItype\fP, int \fIprotocol\fP, void * \fIuser_data\fP)
-.br
-Creates an endpoint for communication and returns a descriptor. \fIdomain\fP, \fItype\fP, and \fIprotocol\fP
-each correspond to the parameters of
-.BR socket(2).
-Returns ahandle to the newly created socket, or -1 on error.
-.TP 18
-.B \fIaclose\fP
-.B int(*)(ares_socket_t \fIfd\fP, void * \fIuser_data\fP)
-.br
-Closes the socket endpoint indicated by \fIfd\fP. See
-.BR close(2)
-.TP 18
-.B \fIaconnect\fP
-.B int(*)(ares_socket_t \fIfd\fP, const struct sockaddr * \fIaddr\fP, ares_socklen_t \fIaddr_len\fP, void * \fIuser_data\fP)
-.br
-Initiate a connection to the address indicated by \fIaddr\fP on a socket. See
-.BR connect(2)
-
-.TP 18
-.B \fIarecvfrom\fP
-.B ares_ssize_t(*)(ares_socket_t \fIfd\fP, void * \fIbuffer\fP, size_t \fIbuf_size\fP, int \fIflags\fP, struct sockaddr * \fIaddr\fP, ares_socklen_t * \fIaddr_len\fP, void * \fIuser_data\fP)
-.br
-Receives data from remote socket endpoint, if available. If the \fIaddr\fP parameter is not NULL and the connection protocol provides the source address, the callback should fill this in. See
-.BR recvfrom(2)
-
-.TP 18
-.B \fIasendv\fP
-.B ares_ssize_t(*)(ares_socket_t \fIfd\fP, const struct iovec * \fIdata\fP, int \fIlen\fP, void * \fIuser_data\fP)

-.fi
-.SH DESCRIPTION
-The \fBares_timeout(3)\fP function determines the maximum time for which the
-caller should wait before invoking \fIares_process(3)\fP to process timeouts.
-The parameter \fImaxtv\fP specifies a existing maximum timeout, or \fBNULL\fP
-if the caller does not wish to apply a maximum timeout.  The parameter
-\fItv\fP must point to a writable buffer of type \fBstruct timeval\fP It is
-valid for \fImaxtv\fP and \fItv\fP to have the same value.
-
-If no queries have timeouts pending sooner than the given maximum timeout,
-\fBares_timeout(3)\fP returns the value of \fImaxtv\fP; otherwise
-\fBares_timeout(3)\fP stores the appropriate timeout value into the buffer
-pointed to by \fItv\fP and returns the value of \fItv\fP.
