-.TH ARES_SAVE_OPTIONS 3 "5 March 2010"
-.SH NAME
-ares_save_options \- Save configuration values obtained from initialized ares_channel
-.SH SYNOPSIS
-.nf
-.B #include <ares.h>
-.PP
-.B int ares_save_options(ares_channel \fIchannel\fP, struct ares_options *\fIoptions\fP, int *\fIoptmask\fP)
-.fi
-.SH DESCRIPTION
-The \fBares_save_options(3)\fP function saves the channel data identified by
-.IR channel ,
-into the options struct identified by
-.IR options ,
-and saves the mask of options which are set to the integer
-pointer (passed by reference) identified by
-.IR optmask .
-
-The resultant options and optmask are then able to be
-passed directly to ares_init_options.  When the options
-are no longer needed, ares_destroy_options should be called
-to free any associated memory.
-.SH RETURN VALUES
-.B ares_save_options(3)
-can return any of the following values:
-.TP 15
-.B ARES_SUCCESS
-The channel data was successfully stored
-.TP 15
-.B ARES_ENOMEM
-The memory was exhausted
-.TP 15
-.B ARES_ENODATA
-The channel data identified by 
-.IR channel
-were invalid.
-.SH NOTE
-Since c-ares 1.6.0 the ares_options struct has been "locked" meaning that it
-won't be extended to cover new functions. This function will remain
-functioning, but it can only return config data that can be represented in
-this config struct, which may no longer be the complete set of config
-options. \fBares_dup(3)\fP will not have that restriction.
-
-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
-used instead.
