NAME

       ares_dup - Duplicate a resolver channel

SYNOPSIS

       #include <ares.h>

       int ares_dup(ares_channel *dest, ares_channel source)

DESCRIPTION

       The  ares_dup(3)  function  duplicates an existing communications channel for name service
       lookups.  If it returns successfully, ares_dup(3) will set the variable pointed to by dest
       to  a  handle  used  to  identify  the  name  service  channel.   The caller should invoke
       ares_destroy(3) on the handle when the channel is no longer needed.

       The ares_dup_options function also initializes a name  service  channel,  with  additional
       options set exactly as the source channel has them configured.
