-.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_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.
