.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).
These functions must be used by integrators choosing not to use the
EventThread enabled via \fBARES_OPT_EVENT_THREAD\fP passed to
\fBares_init_options\fP. This assumes integrators already have their own
event loop handling event notifications for various file descriptors and
wish to do the same with their integration with c-ares.
The \fBares_process(3)\fP function will invoke callbacks for pending queries
if they complete successfully or fail.
The \fBares_process_fds(3)\fP function handles input/output events on file
descriptors and timeouts associated with queries pending on the channel
identified by \fIchannel\fP. The file descriptors to be processed are passed
in an array of \fIares_fd_events_t\fP data structures in the \fIfd\fP member,
and events are a bitwise mask of \fIares_fd_eventflag_t\fP in the \fIevent\fP
member. This function can also be used to process timeouts by passing NULL
to the \fIevents\fP member with \fInevents\fP value of 0. Flags may also be
specified in the \fIflags\fP field and are defined in \fBares_process_flag_t\fP.
\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 avoid \fIselect(3)\fP in their applications and within c-ares.
\fBARES_PROCESS_FLAG_SKIP_NON_FD\fP can be specified to specifically skip any
processing unrelated to the file descriptor events passed in, examples include
timeout processing and cleanup handling. This is useful if an integrator
knows they will be sending multiple \fIares_process_fds(3)\fP requests and
wants to skip that extra processing. However, the integrator must send the
final request with the flag so that timeout and other processing gets performed
before their event loop waits on additional events.
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:
It is allowable to use an \fIares_fd_events_t\fP with \fIevents\fP member of
value \fIARES_FD_EVENT_NONE\fP (0) if there are no events for a given file
descriptor if an integrator wishes to simply maintain an array with all
possible file descriptors and update readiness via the \fIevent\fP member.
.nf
int nfds, count;
fd_set readers, writers;
struct timeval tv, *tvp;
This function will return \fIARES_ENOMEM\fP in out of memory conditions,
otherwise will return \fIARES_SUCCESS\fP.
This function is recommended over \fBares_process_fd(3)\fP since it can
handle processing of multiple file descriptors at once, thus skipping repeating
additional logic such as timeout processing which would be required if calling
\fBares_process_fd(3)\fP for multiple file descriptors notified at the same
time.
This function is typically used with the \fIARES_OPT_SOCK_STATE_CB\fP option.
\fBares_timeout(3)\fP should be used to retrieve the desired timeout, and when
the timeout expires, the integrator must call \fBares_process_fds(3)\fP with
a NULL \fIevents\fP array. (or \fBares_process_fd(3)\fP with both sockets set
to \fIARES_SOCKET_BAD\fP). There is no need to do this if events are also
delivered for any file descriptors as timeout processing will automatically be
handled by any call to \fBares_process_fds(3)\fP or \fBares_process_fd(3)\fP.
The \fBares_process_fd(3)\fP function is the same as \fBares_process_fds(3)\fP
except can only process a single read and write file descriptor at a time.
New integrators should use \fBares_process_fds(3)\fP if possible.
The \fBares_process(3)\fP function works in the same manner, except it works
on \fIfd_sets\fP as is used by \fBselect(3)\fP and retrieved by
\fBares_fds(3)\fP. This method is deprecated and should not be used in modern
applications due to known limitations to the \fBselect(3)\fP implementation.
.SH AVAILABILITY
\fBares_process_fds(3)\fP was introduced in c-ares 1.34.0.

ares_set_pending_write_cb, ares_process_pending_write \- Function
for setting a callback which is triggered when there is potential pending data
which needs to be written.
.SH SYNOPSIS

void ares_set_pending_write_cb(

.fi
.SH DESCRIPTION
The \fBares_set_pending_write_cb(3)\fP function sets a callback
function \fIcallback\fP in the given ares channel handle \fIchannel\fP that
is invoked whenever there is new pending TCP data to be written. Since TCP
is stream based, if there are multiple queries being enqueued back to back they
can be sent as one large buffer. Normally a \fBsend(2)\fP syscall operation
would be triggered for each query.
When setting this callback, an event will be triggered when data is buffered,
but not written. This event is used to wake the caller's event loop which
should call \fBares_process_pending_write(3)\fP using the channel associated
with the callback. Each time the callback is triggered must result in a call
to \fBares_process_pending_write(3)\fP from the caller's event loop otherwise
stalls and timeouts may occur. The callback \fBmust not\fP call
\fBares_process_pending_write(3)\fP directly as otherwise it would invalidate
any advantage of this use-case.
This is considered an optimization, especially when using TLS-based connections
which add additional overhead to the data stream. Due to the asyncronous nature
of c-ares, there is no way to identify when a caller may be finished enqueuing
queries via any of the possible public API calls such as
\fBares_getaddrinfo(3)\fP or \fBares_search_dnsrec(3)\fP, so this is an
enhancement to try to group query send operations together and will rely on the
singaling latency involved in waking the user's event loop.
If no callback is set, data will be written immediately to the socket, thus
bypassing this optimization.
This option cannot be used with \fIARES_OPT_EVENT_THREAD\fP passed to
\fBares_init_options(3)\fP since the user has no event loop. This optimization
is automatically enabled when using the Event Thread as it sets the callback
for its own internal signaling.

This function was first introduced in c-ares version 1.34.0.

As of c-ares 1.24.0, \fBares_set_servers_csv\fP and \fBares_set_servers_ports_csv\fP
are identical. Prior versions would simply omit ports in \fBares_set_servers_csv\fP

.SH DESCRIPTION
.PP
This function sets a set of callback \fIfunctions\fP in the given ares channel handle.
Cannot be used when \fBARES_OPT_EVENT_THREAD\fP is passed to \fIares_init_options(3)\fP.
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. You
can choose to only implement some of the socket functions, and provide NULL to any
others and c-ares will use its built-in system functions in that case.
.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.
\fBares_set_socket_functions_ex(3)\fP sets a set of callback \fIfunctions\fP in
the given ares channel handle. Cannot be used when \fBARES_OPT_EVENT_THREAD\fP
is passed to \fIares_init_options(3)\fP. This function replaces the now
deprecated \fBares_set_socket_functions(3)\fP call.
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.
Some callbacks may be optional and are documented as such below, but failing
to implement such callbacks will disable certain features within c-ares. It
is strongly recommended to implement all callbacks.
All callback functions are expected to operate like their system equivalents,
and to set \fBerrno(2)\fP or \fBWSASetLastError(2)\fP to an appropriate error
code on failure. It is strongly recommended that io callbacks are implemented
to be asynchronous and indicated as such in the \fIflags\fP member. The io
callbacks can return error codes of \fBEAGAIN\fP, \fBEWOULDBLOCK\fP, or
\fBWSAEWOULDBLOCK\fP when they would otherwise block.
The \fIuser_data\fP value is provided to each callback function invocation to
serve as context.
The \fBares_set_socket_functions_ex(3)\fP must provide the following structure
members and callbacks (which are different from the
\fBares_set_socket_functions(3)\fP members and callbacks):
.RS 4
.TP 8
.B unsigned int \fIversion\fP
.br
ABI Version of structure. Must be set to a value of "1".
.TP 8
.B unsigned int \fIflags\fP
.br
Flags available are specified in \fIares_sockfunc_flags_t\fP.
.TP 8
.B ares_socket_t (*\fIasocket\fP)(int \fIdomain\fP, int \fItype\fP, int \fIprotocol\fP, void * \fIuser_data\fP)
.br
\fIREQUIRED\fP. Creates an endpoint for communication and returns a descriptor. \fIdomain\fP,
\fItype\fP, and \fIprotocol\fP each correspond to the parameters of
\fBsocket(2)\fP. Returns a handle to the newly created socket, or
\fBARES_SOCKET_BAD\fP on error.
.TP 8
.B int (*\fIaclose\fP)(ares_socket_t \fIfd\fP, void * \fIuser_data\fP)
.br
\fIREQUIRED\fP. Closes the socket endpoint indicated by \fIfd\fP. See \fBclose(2)\fP.
.TP 8
.B int (*\fIasetsockopt\fP)(ares_socket_t \fIfd\fP, ares_socket_opt_t \fIopt\fP, const void * \fIval\fP, ares_socklen_t \fIval_size\fP, void * \fIuser_data\fP)
.br
\fIREQUIRED\fP. Set socket option. This shares a similar syntax to the BSD \fIsetsockopt(2)\fP
call, however c-ares uses different options for portability. The value is
a pointer to the desired value, and each option has its own data type listed
in the options below defined in \fIares_socket_opt_t\fP.
.TP 8
.B int (*\fIaconnect\fP)(ares_socket_t \fIfd\fP, const struct sockaddr * \fIaddr\fP, ares_socklen_t \fIaddr_len\fP, unsigned int \fIflags\fP, void * \fIuser_data\fP)
.br
\fIREQUIRED\fP. Initiate a connection to the address indicated by \fIaddr\fP on
a socket. Additional flags controlling behavior are in
\fIares_socket_connect_flags_t\fP. See \fBconnect(2)\fP.
.TP 8
.B ares_ssize_t (*\fIarecvfrom\fP)(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
\fIREQUIRED\fP. 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. The \fIflags\fP parameter is
currently unused. See \fBrecvfrom(2)\fP.
.TP 8
.B ares_ssize_t (*\fIasendto\fP)(ares_socket_t \fIfd\fP, const void * \fIbuffer\fP, size_t \fIlength\fP, int \fIflags\fP, const struct sockaddr * \fIaddress\fP, ares_socklen_t \fIaddress_len\fP, void * \fIuser_data\fP)
.br
\fIREQUIRED\fP. Send data, as provided by the \fIbuffer\fP, to the socket
endpoint. The \fIflags\fP member may be used on systems that have
\fBMSG_NOSIGNAL\fP defined but is otherwise unused. An \fIaddress\fP is
provided primarily to support TCP FastOpen scenarios, which will be NULL in
other circumstances. See \fBsendto(2)\fP.
.TP 8
.B int (*\fIagetsockname\fP)(ares_socket_t \fIfd\fP, struct sockaddr * \fIaddress\fP, ares_socklen_t * \fIaddress_len\fP, void * \fIuser_data\fP)
.br
\fIOptional\fP. Retrieve the local address of a socket and store it into the provided
\fIaddress\fP buffer. May impact DNS Cookies if not provided. See
\fBgetsockname(2)\fP.
.TP 8
.B int (*\fIabind\fP)(ares_socket_t \fIfd\fP, unsigned int \fIflags\fP, const struct sockaddr * \fIaddress\fP, ares_socklen_t \fIaddress_len\fP, void * \fIuser_data\fP)
.br
\fIOptional\fP. Bind the socket to an address. This can be used for client
connections to bind the source address for packets before connect, or
for server connections to bind to an address and port before listening.
Currently c-ares only supports client connections. \fIflags\fP from
\fIares_socket_bind_flags_t\fP can be specified. See \fBbind(2)\fP.
.TP 8
.B unsigned int (*\fIaif_nametoindex\fP)(const char * \fIifname\fP, void * \fIuser_data\fP)
.br
\fIOptional\fP. Convert an interface name into the interface index. If this
callback is not specified, then IPv6 Link-Local DNS servers cannot be used.
See \fBif_nametoindex(2)\fP.
.TP 8
.B const char * (*\fIaif_indextoname\fP)(unsigned int \fIifindex\fP, char * \fIifname_buf\fP, size_t \fIifname_buf_len\fP, void * \fIuser_data\fP)
.br
\fIOptional\fP. Convert an interface index into the interface name. If this
callback is not specified, then IPv6 Link-Local DNS servers cannot be used.
\fIifname_buf\fP must be at least \fBIF_NAMESIZE\fP or \fBIFNAMSIZ\fP in size.
See \fBif_indextoname(2)\fP.
