ARES_DUP(3)           DragonFly Library Functions Manual           ARES_DUP(3)

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.

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