ares_dup - Duplicate a resolver channel

 #include <ares.h> 

 int ares_dup(ares_channel *dest, ares_channel source) 

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. ares_destroy(3), ares_init(3), ares_library_init(3) ares_dup(3) was added in c-ares 1.6.0 Daniel Stenberg
