+.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 \fIrd\fP,
+                      unsigned char **\fIbuf\fP,
+                      int *\fIbuflen\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 AVAILABILITY
+Added in c-ares 1.10.0
