.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.
