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.
