.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, but
before it has been connected to the remote server, which is an ideal time
to configure various socket options.  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.
