                                         void * userdata)

This function sets a callback in the given ares channel handle. This callback function will be invoked after the socket has been created, and connected to the remote server. The callback must return ARES_SUCCESS if things are fine, or return -1 to signal an error. A returned error will abort the ares operation.
