#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.
