+.TH ARES_INIT 3 "5 March 2010"
+.SH NAME
+ares_init \- Initialize a resolver channel
+.SH SYNOPSIS
+.nf
+#include <ares.h>
+
+int ares_init(ares_channel *\fIchannelptr\fP)
+.fi
+.SH DESCRIPTION
+The \fBares_init(3)\fP function initializes a communications channel for name
+service lookups.  If it returns successfully, \fBares_init(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 \fIares_init_options(3)\fP function is provide to offer more init
+alternatives.
+.SH RETURN VALUES
+\fIares_init(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,
+.BR ares_init (3)
+reads the
+.I domain
+and
+.I search
+directives to allow lookups of short names relative to the domains
+specified. The
+.I domain
+and
+.I search
+directives override one another. If more that one instance of either
+.I domain
+or
+.I search
+directives is specified, the last occurrence wins. For more information,
+please see the
+.BR resolv.conf (5)
+manual page.
