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.

AVAILABILITY
       ares_dup(3) was added in c-ares 1.6.0
