.SH DESCRIPTION
.PP
This function sets a \fIcallback\fP 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.
