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.

SEE ALSO
       ares_destroy(3), ares_init(3), ares_library_init(3)

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